[0002] Japanese Patent Publication No. 2017-510715 states, "The present invention relates to martensitic-ferritic stainless steel used in the manufacture of steel products such as tubing and casing for applications in the oil and gas industries, where high mechanical strength (typically a yield limit exceeding 552 MPa (80 ksi)) and toughness are required in combination with excellent corrosion resistance. NACE MR0175 and ISO 15156 standards provide guidance for the selection of corrosion-resistant alloys (CRAs) based on material groups including application (equipment or component) and manufacturing processes, and ultimately on environmental parameters such as temperature and partial pressure of H2S."

[0003] In crude oil and natural gas extraction, the pipes used to pump crude oil and natural gas from underground to the surface, or to supply fluids and gases from the surface to underground, are called tubing.

[0031] Hereinafter, an example of an embodiment of this disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components and parts are given the same reference numerals. Also, the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0032] Figure 1 shows an example of the schematic configuration of the information processing system 1 according to this embodiment. The information processing system 1 is designed to lease oil well pipes. The information processing system 1 is designed to provide information that contributes to objective pricing when leasing oil well pipes.

[0033] Oil well pipes (pipes for oil and gas wells) are steel pipes used in the extraction of crude oil and natural gas. Oil well pipes used to pump crude oil and gas from underground reservoirs to the surface, or to supply fluids and gases from the surface to underground (such as carbon dioxide injection for CCS (Carbon Capture and Storage), and stimulation to activate reservoirs) are called tubing. Oil well pipes are also increasingly being used in geothermal and lithium development. Oil well pipes that surround the tubing to prevent the collapse of geological formations are called casings. The information processing system 1 according to this embodiment may lease such oil well pipes (tubing and casings).

[0034] As mentioned above, CRA tubing, which possesses corrosion resistance, is known as a type of tubing. While corrosion resistance extends the lifespan of the tubing, it also increases the initial cost. Even though it is known that replacing conventional carbon steel or sour-resistant steel with CRA tubing can reduce life cycle costs, the initial cost is a major obstacle to such replacement. Therefore, such CRA tubing is particularly well-suited to lease agreements. Accordingly, it is especially preferable for the information processing system 1 according to this embodiment to lease tubing that possesses higher corrosion resistance than conventional carbon steel or sour-resistant steel, such as CRA tubing.

[0035] The information processing system 1 includes a server device 10, a terminal device 20, a specification database 30, and a history database 40. These are communicably connected to each other via communication means 50. As an example, the communication means 50 may be the Internet. However, it is not limited thereto. The communication means 50 may be any means capable of communicably connecting a plurality of computers, such as a LAN (Local Area Network), a WAN (Wide Area Network), or an intranet.

[0036] The server device 10 receives a request from the terminal device 20 and transmits data and execution results corresponding to the request to the terminal device 20. As an example, the server device 10 may be realized by cloud computing. In this figure, the case where the server device 10 is one device is shown as an example. However, the server device 10 may perform distributed processing of a plurality of processes by a plurality of devices.

[0037] The terminal device 20 transmits a request to the server device 10 and receives data and execution results corresponding to the request from the server device 10. As an example, the terminal device 20 may be a desktop personal computer, a notebook personal computer, a tablet, a smartphone, or the like. Similarly to the server device 10, the terminal device 20 may perform distributed processing of a plurality of processes by a plurality of devices.

[0038] The specification database 30 stores specification data indicating the specifications of oil well pipes. Details of the specification data stored in the specification database will be described later.

[0039] The history database 40 stores history data indicating the history of past use of oil well pipes. Details of the history data stored in the history database will be described later.

[0040] Hereinafter, a case where the information processing system 1 is configured as a Web (World Wide Web) system will be described as an example. In the case of a Web system, on the terminal device 20 side, data and programs are not held, and programs are processed collectively on the server device 10 side. In this case, the information processing device 100 that is the operating entity that executes the information processing according to the present embodiment may be the server device 10. However, it is not limited to this.

[0041] The information processing system 1 may be configured as a client-server system. In the case of a client-server system, since data and programs are held on the terminal device 20 side, programs are processed on the terminal device 20 side. In this case, the information processing device 100 that is the operating entity that executes the information processing according to the present embodiment may be the terminal device 20. That is, the information processing according to the present embodiment may be executed in any of the information processing systems 1, may be processed on the network side, or may be processed on the terminal side. Further, the information processing according to the present embodiment may be processed distributively on the network side and the terminal side.

[0042] For example, when the information processing device 100 is the server device 10, the information processing system 1 may include the information processing device 100 and a terminal device 20 communicably connected to the information processing device 100 via a network. Then, the terminal device 20 may receive input of environmental data from the user, transmit the environmental data to the information processing device 100, and receive information corresponding to the lease fee from the information processing device 100 and display it on the monitor.

[0043] In this case, the physical location of the information processing device 100 is not particularly limited. That is, all or part of the information processing device 100 may be installed in any location, domestically or internationally, and may be configured via a remotely installed server or data center. Furthermore, the information processing system 1 of this disclosure includes forms that can be implemented not only in the country or region where the information processing device 100 is installed, but also in the country or region where the terminal device 20 is installed. That is, even if the information processing device 100 is installed abroad, it includes forms in which the functions or effects of this disclosure are manifested in the country or region where the terminal device 20 is installed, and conversely, even if the terminal device 20 is installed abroad, it includes forms in which the functions or effects of this disclosure are manifested in the country or region where the information processing device 100 is installed. Thus, this disclosure is configured as a distributed information processing system that can be implemented in either the country or region of the server device 10 or the terminal device 20.

[0044] Furthermore, the information processing device 100 may update the database used to determine the lease fee as needed based on input from the terminal device 20. In this case, when new environmental data or current data is received from the terminal device 20, the database records can be updated to reflect that data. This makes it possible to determine the lease fee based on data that reflects the latest on-site information, thereby improving the accuracy and adaptability of the determination.

[0045] Figure 2 shows an example of the hardware configuration of the information processing device 100 according to this embodiment. The information processing device 100 includes a processor 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a storage 104, and an interface 105. These components are connected to each other so as to be able to communicate with one another via a bus 109.

[0046] The processor 101 executes various programs and controls each component. The processor 101 may be, for example, a CPU (Central Processing Unit).

[0047] ROM 102 stores various programs and data. RAM 103 temporarily stores programs or data as a working area. Storage 104 is composed of an HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs and data, including the operating system. Note that storage 104 may be cloud storage that can store programs and data on the internet.

[0048] In the information processing device 100, the information processing program 106 is stored in the ROM 102 or storage 104. In this figure, the case where the information processing program 106 is stored in the storage 104 is shown as an example. The processor 101 reads the information processing program 106 from the ROM 102 or storage 104 and executes it using the RAM 103 as a working area, thereby controlling each configuration and performing various calculations according to the information processing program 106.

[0049] Interface 105 is an input / output unit for the information processing device 100 to exchange information with the outside world. Interface 105 may include a communication interface for communicating with other devices and a user interface for exchanging information with a user.

[0050] Figure 3 shows an example of the functional configuration of the information processing device 100 according to this embodiment. The information processing device 100 includes an environment data acquisition unit 110, a specification data acquisition unit 120, a history data acquisition unit 130, a determination unit 140, an output unit 150, and a history data update unit 160. These functional configurations may be implemented in the information processing device 100 by the processor 101 reading the information processing program 106 from the ROM 102 or storage 104, expanding it into the RAM 103, and executing it.

[0051] The environmental data acquisition unit 110 is a functional unit for acquiring environmental data. The specification data acquisition unit 120 is a functional unit for acquiring specification data. The history data acquisition unit 130 is a functional unit for acquiring history data. The determination unit 140 is a functional unit for determining the lease fee. The output unit 150 is a functional unit for outputting information corresponding to the lease fee. The history data update unit 160 is a functional unit for updating history data.

[0052] Before describing the information processing performed by the information processing device 100 equipped with such functional units, we will first describe in detail the environmental data, specification data, and history data used by the information processing device 100 for information processing.

[0053] Figures 4 to 6 show examples of input screens used by the information processing device 100 according to this embodiment. When determining the lease fee, the processor 101 may display input screens as shown in these figures on the terminal device 20.

[0054] Figure 4 shows an example of a first input screen used by the information processing device 100 according to this embodiment. The processor 101 may display the first input screen on the terminal device 20 and accept input of environmental data, which is data indicating the environmental conditions for using the oil well pipe. The entity that inputs such data may be the user who wishes to enter into a lease agreement, or the leasing company (for example, a sales representative who has heard the user's wishes).

[0055] The first input screen includes, as an example, "Period", "Region", "Land / Sea", and "CO ２ Partial pressure, H ２ Items such as "partial pressure," "depth," and "temperature" may be included.

[0056] The "Period" field is for inputting the period during which the oil well tubular goods will be used. The processor 101 may accept input for the start and end dates of the desired lease period through this field.

[0057] The "Region" field is for inputting the region in which the oil well pipe will be used. The processor 101 may accept input such as the name (including the field name) or country name of the oil field, gas field, or oil-gas field in which the oil well pipe will be used.

[0059] "CO ２ The "partial pressure" field is for inputting the partial pressure of carbon dioxide in an environment where oil well pipes are used. The processor 101 may accept input of an expected value for the partial pressure of carbon dioxide (average or maximum value, etc.), such as 1 MPa or 10 bar, through this field.

[0060] "H ２ "S partial pressure" is an item for inputting the hydrogen sulfide partial pressure in an environment where oil well pipes are used. Processor 101 then processes this item. －１ The system may accept input values ​​for the expected hydrogen sulfide partial pressure (average or maximum value, etc.), such as MPa or 1 bar.

[0062] The "Temperature" field is for inputting the temperature in the environment where the oil well pipe is used. The processor 101 may accept input of an expected temperature value (average or maximum value, etc.), such as 180°C, through this field.

[0063] The processor 101 may, for example, obtain environmental data indicating the environmental conditions for using the oil well pipe from the terminal device 20 via the communication means 50. Note that this figure only shows an example of data that can be used as environmental data; not all of the data shown in this figure is necessarily used, and other data not shown in this figure may be used. Furthermore, if the environmental conditions are unknown to the user, this input may be skipped, and the leasing company may input the data after being inquired about.

[0064] Figure 5 shows an example of a second input screen used by the information processing device 100 according to this embodiment. The processor 101 may display the second input screen on the terminal device 20 and accept input of desired data, which is data relating to oil well tubular goods for which a lease agreement is desired.

[0065] The second input screen may include items such as "Size," "Grade," and "Screw Type," as an example. Each item may also have a pull-down button to display predefined options.

[0066] The "Size" field is for inputting the dimensions of the oil well pipe, and may include sub-fields such as "Diameter" and "Wall Thickness." The processor 101 may accept input for the diameter of the oil well pipe, for example, "7 5 / 8," using the "Diameter" field.

[0067] The "wall thickness" field is for inputting the weight per unit length. The processor 101 may accept input for the weight per unit length (wall thickness) of the oil well pipe, for example, "24.00 lb / ft (pounds per foot)," through the "wall thickness" field. (The wall thickness may also be in millimeters.)

[0068] The "Grade" field is for inputting a grade indicating the material (e.g., alloy composition grade) or properties (e.g., strength grade) of the oil well tubular material. The processor 101 may accept input of a manufacturer's proprietary grade, such as "SM2535," or it may accept input of a grade defined by a standard, such as "API 5CT J55."

The processor 101 may display the third input screen on the terminal device 20 and accept input of current data, which is data relating to the oil well pipe currently in use.

[0071] The third input screen may include items such as "Grade" and "Screw Type." Each item may have a pull-down button to display predetermined options. Buttons may also be provided to skip input for the "Grade" and "Screw Type" items.

[0072] Figure 7 shows an example of specification data used by the information processing device 100 according to this embodiment. The specification database 30 may store data such as that shown in this figure as specification data.

[0073] Specification data is data that shows the specifications of the oil well tubular goods. Specification data may include data such as "chemical composition" and "mechanical properties". "Chemical composition" may be data showing the chemical composition for each grade. Such data may include data showing the content of each element, such as "carbon (C)", "nickel (Ni)", "chromium (Cr)", and "molybdenum (Mo)".

[0074] "Mechanical properties" may refer to data showing the mechanical properties for each size within each grade. Such data may include, for example, data showing properties such as "yield strength," "tensile strength," "elongation," "hardness," "creep strength," and "toughness." Since these properties are known as data indicating the specifications of oil well pipes, a detailed explanation is omitted here.

[0075] The information processing device 100 may, for example, obtain specification data indicating the specifications of such an oil well pipe from the specification database 30 via the communication means 50. Note that this figure is merely an example of data that can be used as specification data, and not all of the data shown in this figure is necessarily used, and other data not shown in this figure may also be used.

[0076] Figure 8 shows an example of history data used by the information processing device 100 according to this embodiment. The history database 40 may store data such as that shown in this figure as history data.

[0077] Historical data is data that shows the history of past use of oil well tubular goods. Such data may include information such as "identification information," "grade," "size," "manufacturer," "manufacturing date," "contractor," "movement history," "connection / disconnection count," "environmental conditions," and "inspection information."

[0078] "Identification information" refers to information that indicates an identifier that uniquely identifies an oil well pipe. Identification information may be attached to the oil well pipe in advance (for example, during manufacturing). Such identification information may be printed on the oil well pipe in a manner that creates a textured surface by processing the pipe itself, such as by laser stenciling, laser QR code (QR code is a registered trademark), electric pen, or vibro-etching. Historical data may be recorded in association with the identification information attached to the oil well pipe in this manner.

[0079] "Grade" is data indicating the grade of the oil well tubular construction. "Size" is data indicating the dimensions of the oil well tubular construction, such as the outer diameter and wall thickness. "Manufacturer" is data indicating the factory where the oil well tubular construction was manufactured. "Manufacturing date" is data indicating the year and month the oil well tubular construction was manufactured. "Contractor" is data indicating the party that previously leased the oil well tubular construction. "Movement history" is data indicating the movement history of the oil well tubular construction. "Connection / Disconnection count" is data indicating the number of times the oil well tubular construction has been made up or broken out.

[0080] "Environmental conditions" is data indicating the environmental conditions under which the oil well tubular goods were previously used. As described later, environmental data may be recorded in "Environmental conditions" when a lease agreement is concluded. "Inspection information" is data indicating the details and results of inspections of the oil well tubular goods conducted after the expiration of the lease agreement.

[0081] Of this data, the "identification information," "grade," "size," "manufacturer," and "manufacturing date" may be recorded in the history database 40 at the time of manufacturing of the oil well tubular cargo. On the other hand, the "contractor," "movement history," "connection / disconnection count," "environmental conditions," and "inspection information" may be left blank at the time of manufacturing of the oil well tubular cargo, and may be added at the time of the lease agreement or after the lease agreement expires if the oil well tubular cargo is leased.

[0082] The information processing device 100 may, for example, obtain historical data showing the history of past use of such oil well pipes from the history database 40 via the communication means 50. Note that this figure only shows an example of data that can be used as historical data, and not all of the data shown in this figure is necessarily used, and other data not shown in this figure may also be used.

[0083] The information processing device 100 according to this embodiment may perform information processing using such various data. This will be explained in detail using a flowchart.

[0084] Figure 9 shows an example of the information processing flow executed by the information processing device 100 according to this embodiment. This flow may be started when the processor 101 reads the information processing program 106 from the ROM 102 or storage 104, loads it into the RAM 103, and executes it.

[0085] In step S210, the processor 101, acting as an environmental data acquisition unit 110, acquires environmental data. The processor 101 may, for example, display the first input screen shown in Figure 4 on the terminal device 20 via the interface 105. In response, the processor 101 may accept data input.

[0086] In this case, the processor 101 may set mandatory and optional items for the environmental conditions. For example, if the name of the oil field entered in "Region" makes it clear whether the extraction site is onshore or offshore, the processor 101 may set the "Land / Sea" item as an optional item. On the other hand, since carbon dioxide partial pressure, hydrogen sulfide partial pressure, and temperature are important factors for oil well tubular goods, the processor 101 may set "CO ２ Partial pressure, H ２ The items "Partial Pressure" and "Temperature" may be made mandatory.

[0087] When data is entered into the first input screen, the processor 101 acquires the entered data as environmental data. For example, the processor 101 can acquire environmental data indicating the environmental conditions for using the oil well pipe from the terminal device 20 via the communication means 50 in this manner.

[0088] When the "Next" button is pressed on the first input screen, the processor 101 may display the second input screen shown in Figure 5 on the terminal device 20 via the interface 105. In response, the processor 101 may accept data input.

[0089] When data is entered into the second input screen, the processor 101 acquires the entered data as desired data. For example, the processor 101 can acquire desired data, which is data relating to oil well tubular goods for which a lease agreement is desired, from the terminal device 20 via the communication means 50.

[0090] When the "Next" button is pressed on the second input screen, the processor 101 may display the third input screen shown in Figure 6 on the terminal device 20 via the interface 105. In response, the processor 101 may accept data input.

[0091] When data is entered into the third input screen, the processor 101 acquires the entered data as current data. For example, the processor 101 can acquire current data, which is data relating to the oil well tubular goods currently in use, from the terminal device 20 via the communication means 50 in this manner.

[0092] When the "Next" button is pressed on the third input screen, the processor 101 may proceed to the next step.

[0093] In step S220, the processor 101, acting as a specification data acquisition unit 120, acquires specification data. The processor 101 may, for example, access the specification database 30 via the interface 105. The processor 101 may then acquire, for example, the data shown in Figure 7 from the specification database 30 via the communication means 50. In this way, the processor 101 can acquire specification data indicating the specifications of the oil well pipe.

[0094] In step S230, the processor 101, acting as a history data acquisition unit 130, acquires history data. The processor 101 may, for example, access the history database 40 via the interface 105. The processor 101 may then acquire, for example, the data shown in Figure 8 from the history database 40 via the communication means 50. In this way, the processor 101 can acquire history data showing the history of past use of the oil well tubular block.

[0095] In step S240, the processor 101, acting as a determination unit 140, determines the lease fee. First, the processor 101 identifies the oil well tubular goods to be leased. In this case, the processor 101 may identify the oil well tubular goods to be leased based on the desired data obtained in step S210. If the desired data includes all the data for "size," "grade," and "thread type," the processor 101 may identify the oil well tubular goods to be leased according to the desired data.

[0096] On the other hand, if the requested data does not include data for at least one of "grade" and "thread type," the processor 101 may identify at least one of the recommended oil well pipe grades and thread types based on the environmental data and specification data.

[0097] In this case, the processor 101, for example, selects "CO" from the environmental data acquired in step S210. ２ Partial pressure, H２ Focusing on the data of "CO partial pressure" and "temperature", at least one of the grade and thread type of the recommended oil well pipe may be specified according to a predetermined branching condition.

[0098] For example, suppose the data of "CO ２ partial pressure" is a value greater than 20 kPa, and the data of "H ２ S partial pressure" is a value greater than 10 kPa. In this case, the processor 101 may determine to recommend a nickel alloy oil well pipe.

[0099] Also, suppose the data of "temperature" is a value of 149 °C or less. In this case, the processor 101 may determine to recommend a product containing about 3% molybdenum as the oil well pipe. Then, the processor 101 may refer to the "chemical composition" among the specification data acquired in step S220. Here, the processor 101 may specify "SM2535" with a molybdenum content ratio of 2.50 to 4.00 among nickel alloy oil well pipes as the grade of the recommended oil well pipe. The processor 101 may similarly specify the thread type according to a predetermined branching condition.

[0100] When the processor 101 specifies the oil well pipe to be leased in this way, for example, it may determine the base fee that forms the basis of the lease fee according to the specified oil well pipe. Such a base fee may be predetermined based on the manufacturing cost (for example, raw materials, etc.) for each oil well pipe.

[0101] Here, suppose the oil well pipe to be leased is a reused product that has been used in the past. In this case, the processor 101 may determine the residual value of the oil well pipe as the base fee. At this time, the processor 101 may calculate the residual value based on the history data acquired in step S230. The calculation of the residual value will be described later. The processor 101 can determine the base fee that forms the basis of the lease fee based on the history data in this way, for example.

[0102] Next, the processor 101 may identify the oil well tubular construction currently in use. In this case, the processor 101 may identify the oil well tubular construction currently in use based on the current data acquired in step S210. If the current data includes all data for "grade" and "thread type", the processor 101 may identify the oil well tubular construction currently in use according to the current data. Regarding the size, the "size" data from the desired data may be used as is.

[0103] On the other hand, if the current data does not include data on at least one of "grade" and "thread type," the processor 101 may identify at least one of the grade and thread type of the oil well pipe currently expected to be in use, based on the environmental data.

[0104] For example, the processor 101 may, for instance, focus on the "region" data among the environmental data acquired in step S210 and identify at least one of the grade and thread type of oil well tubulars expected to be in use in each region, based on the usage history of oil well tubulars in each region.

[0105] The processor 101 may then predict the life cycle cost of the oil well tubular construction currently in use or expected to be used, assuming it continues to be used under the environmental conditions indicated in the environmental data. Here, it is assumed that the grade of the oil well tubular construction currently in use is identified as "sour-resistant steel".

[0106] In this case, the processor 101 may read the data for "SM-110XS" corresponding to "sour-resistant steel" from the specification data acquired in step S220. Then, the processor 101 may extract data from the "SM-110XS" data whose size matches the desired data.

[0107] The processor 101 may then calculate the expected workover frequency for tubing replacement if the oil well tubing with such specifications continues to be used under the environmental conditions indicated by the environmental data. Based on the workover frequency, the processor 101 may then predict the life cycle cost.

[0108] In this case, the processor 101 may estimate the workload cost per operation based on the "region" and "land / sea" data in the environmental data. For example, the processor 101 may estimate the workload cost to be higher when a location with a high access cost is entered for "region" than when a location with a low access cost is entered.

[0109] Similarly, the processor 101 may estimate that the workload costs will be higher when offshore is selected in the "land / sea" scenario than when onshore is selected. The processor 101 may then predict the life cycle cost by multiplying the workload cost by the workload frequency.

[0110] The processor 101 may then determine the lease fee by adding a portion of the life cycle cost predicted in this way to the base fee. For example, the processor 101 can use environmental data to predict the life cycle cost of continuing to use oil well tubulars currently in use or expected to be used under environmental conditions, and then determine the lease fee based on the life cycle cost.

[0111] When using tubing with a short lifespan, it is necessary to perform a workover and replace the tubing every few years. This incurs transportation costs to access the mining site, as well as rental fees for the rig. On the other hand, when using corrosion-resistant tubing such as CRA tubing, the frequency of tubing replacement can be reduced. Therefore, even if the lease fee is higher, the user can enjoy the benefits of leasing the tubing. This creates a win-win relationship between the user and the leasing company.

[0112] Furthermore, if the oil well tubular goods are used under harsh environmental conditions during the lease agreement, it is possible that the next user wishing to lease them may be hesitant due to concerns about the deterioration of the oil well tubular goods. The deterioration of oil well tubular goods can be caused by general corrosion and SCC (Stress Corrosion Cracking). Therefore, the processor 101 may calculate the residual value of the oil well tubular goods after the lease agreement expires, based on environmental data.

[0113] For example, processor 101 processes "CO2" in environmental data. ２ "Partial pressure" and "H ２ When the "S partial pressure" data is a large value, the residual value may be calculated in such a way that it is smaller than when the value is small. Similarly, when the "depth" and "temperature" data in the environmental data are large values, the processor 101 may calculate the residual value in such a way that it is smaller than when the values ​​are small.

[0114] In addition, the processor 101 may calculate the residual value by also considering other factors such as moisture content, salt concentration, bicarbonate concentration, and ion concentration. The processor 101 may then determine the lease fee by adding an additional charge inversely proportional to the residual value to the base fee.

[0115] Finally, the processor 101 may calculate an adjustment fee taking into account interest rates, insurance premiums, market conditions, and sales strategies. Then, the processor 101 may determine the final lease payment by applying the adjustment fee.

[0116] The processor 101 can determine the lease fee for the oil well tubular waste based on environmental data, for example, in this manner. More specifically, the processor 101 may use the environmental data to predict the life cycle cost of continuing to use the oil well tubular waste currently in use or expected to be used under environmental conditions, and determine the lease fee based on the life cycle cost.

[0117] Furthermore, the processor 101 can also determine the lease fee based on historical data. More specifically, the processor 101 may calculate the residual value based on historical data and determine the residual value as the base fee that forms the basis of the lease fee.

[0118] Furthermore, the processor 101 can also determine the lease fee based on the specification data. More specifically, the processor 101 may use the specification data to identify the grade of the oil well tubular material that meets the environmental conditions, and then determine the base fee that forms the basis of the lease fee based on the grade.

[0119] In step S250, the processor 101 outputs information corresponding to the lease fee as an output unit 150. The processor 101 may display, for example, the output screen shown below on the terminal device 20 via the interface 105.

[0120] Figure 10 shows an example of an output screen output by the information processing device 100 according to this embodiment. As shown in this figure, the processor 101 may output the grade of the oil well tubular vessel to be leased. Here, the case where the grade of the oil well tubular vessel to be leased is "SM2535" is shown as an example.

[0121] Furthermore, the processor 101 may output information necessary to view the usage history of the leased oil well tubular goods. In the case of new goods, a history may not be necessary, but it may include transportation history and storage history. In this case, the processor 101 may output a link to access the history, or it may output a QR code to access the history. Here, let's assume that the grade of the oil well tubular goods to be leased is "SM2535" and the size is "7 5 / 8" inches, so the processor 101 identified the oil well tubular goods with identification information "0002" as the leased item. In this case, the processor 101 may output a link or a QR code to access the history data associated with identification information "0002".

[0122] Furthermore, the processor 101 may output the lease fee for the oil well tubular goods to be leased. In this figure, the case in which the processor 101 outputs the monthly lease fee is shown as an example. Note that in this figure, the case in which the processor 101 outputs the determined lease fee as is is shown as an example, but it is not limited to this. The processor 101 may output a price range that includes the determined lease fee, or it may output a rank corresponding to the price range.

[0123] Furthermore, the processor 101 may output the cost savings expected if a lease agreement is made at the determined lease rate. In this figure, one example is shown where the processor 101 outputs a message to the effect that "compared to the tubes you are currently using, a cost reduction of **** US dollars is expected by the end of the lease term." As an example, the processor 101 may calculate the cost savings expected if a lease agreement is made at the lease rate, that is, if the oil well tubulars are replaced from the currently used "sour-resistant steel" to "SM2535," based on the calculated life cycle cost, and output that cost.

[0124] Furthermore, the processor 101 may output a button that allows the user to select whether or not to proceed with the lease agreement. The processor 101 can output information corresponding to the lease fee in this manner, for example.

[0125] Note that the above explanation used the case where there is only one leaseable tubular well as an example. However, if there are multiple leaseable tubular wells, the processor 101 may output this information for each tubular well. Returning to the explanation of Figure 9.

[0126] In step S260, the processor 101, acting as an output unit 150, determines whether or not there is a request to view the data. The user can request to view the history data by clicking a link on the output screen or by scanning a QR code. If it is determined that there is a request to view the data, the processor 101 proceeds to step S270. On the other hand, if it is determined that there is no request to view the data, the processor 101 omits the processing in step S270.

[0127] In step S270, the processor 101, as an output unit 150, discloses the history data to the user. Here, the history data includes data related to trade secrets such as "contractor". In this case, the processor 101 may mask such data related to trade secrets and display it on the terminal device 20. The processor 101 may, for example, disclose a portion of the history data with a mask in response to a request to view the history data.

[0128] In this case, the oil well tubular goods available for lease may include both new and used items, but the lease fee will naturally be higher for new items than for used items. In this situation, the user can appropriately choose whether to lease used or new items, taking into account the usage history and lease fees.

[0129] In step S280, the processor 101, as the output unit 150, determines whether or not a contract has been concluded. The user can request a quote from the leasing company by pressing the "Yes" button on the output screen. If a contract has been concluded, the processor 101 proceeds to step S290. On the other hand, if no contract has been concluded, the processor 101 skips the processing in step S290 and terminates the process.

[0130] In step S290, the processor 101, acting as a history data update unit 160, updates the history data. The processor 101 may, for example, access the history database 40 via the interface 105. The processor 101 may then update the history data by writing the environmental data acquired in step S210 to the "environmental conditions" item associated with the corresponding identification information. Here, the processor 101 may update the history data by writing the environmental data acquired in step S210 to the environmental conditions item where the identification information is "0002". The processor 101 may, for example, record the environmental data and update the history data in this manner when a lease agreement is concluded. The processor 101 then terminates this flow.

[0131] As described above, the information processing device 100 according to this embodiment acquires environmental data indicating the environmental conditions under which oil well pipes are used, determines the lease fee for leasing the oil well pipes based on the environmental data, and outputs information corresponding to the lease fee. Thus, according to the information processing device 100 according to this embodiment, it is possible to provide information that contributes to objective pricing when leasing oil well pipes.

[0132] Generally, CRA tubing does not require replacement and can be used for long-term operation of 10 years or more. In contrast, conventional low-alloy steel tubing requires a workover every few years to replace the tubing. Workovers involve stopping production, preparing the rig, and incurring enormous costs. Therefore, using CRA tubing can sometimes reduce life cycle costs compared to using low-alloy steel tubing. However, CRA tubing has high initial costs (for example, 10 times that of conventional low-alloy steel tubing), and the reality is that there are manufacturers who want to use it but cannot.

[0133] To address these issues, the information processing device 100 according to this embodiment can provide information that contributes to objective pricing when leasing oil well pipes, thereby contributing to the creation of a new business model for leasing oil well pipes.

[0134] While the business of renting drill pipes for drilling is known, drill pipes are used only temporarily during drilling and are completely different from oil well tubular goods, which are used continuously during production. A business model that includes such oil well tubular goods as part of a lease agreement is a completely new model that differs from existing businesses.

[0135] Furthermore, the information processing device 100 may acquire historical data showing the history of past use of the oil well tubular goods, and may determine the lease fee based on this historical data. This allows the information processing device 100 to determine different lease fees depending on whether the oil well tubular goods are new, nearly new, or reused, even if they are of the same grade. Additionally, the information processing device 100 can determine different lease fees depending on the differences in the environments in which they were previously used, even if they are reused items of the same grade.

[0136] Furthermore, identification information may be attached to the oil well pipes, and the history data may be recorded in association with this identification information. In this case, the identification information may be printed on the oil well pipe in a manner that creates irregularities by processing the pipe itself. This allows the information processing device 100 to manage the history consistently from manufacturing to scrap, utilizing advanced traceability. In this case, it is more preferable if the identification information is applied to the pipe itself by processing, as this prevents the identification information from being erased.

[0137] Furthermore, the information processing device 100 may record environmental data and update the historical data when a lease agreement is concluded. This means that the information processing device 100 provides a mechanism to automatically update the historical data in accordance with the lease agreement, thus saving the leasing company the trouble of manually entering the historical data.

[0138] Furthermore, the information processing device 100 may, in response to a request to view the history data, mask and disclose a portion of the history data. This allows the information processing device 100 to prevent third parties from viewing information related to trade secrets, even if the history data contains such information.

[0139] Furthermore, the information processing device 100 may use environmental data to predict the life cycle cost of continuing to use oil well pipes currently in use or expected to be used under environmental conditions, and determine the lease fee based on the life cycle cost. In this way, the information processing device 100 can establish a win-win relationship between the user and the leasing company.

[0140] Furthermore, the information processing device 100 may calculate the expected cost reductions based on the life cycle cost when a lease agreement is made, and output these costs. This allows the information processing device 100 to present the user with the actual benefits that can be enjoyed through a lease agreement, thereby motivating the user to actively enter into a lease agreement.

[0141] Furthermore, the information processing device 100 may acquire specification data indicating the specifications of the oil well pipe and determine the lease fee based on the specification data. In this case, the information processing device 100 may use the specification data to identify the grade of oil well pipe that meets the environmental conditions and determine the lease fee based on the grade. As a result, the information processing device 100 can determine the lease fee even if the input of data regarding the desired oil well pipe is insufficient.

[0142] This allows users to utilize corrosion-resistant tubing, such as CRA tubing, within an economical budget without incurring enormous initial costs, thereby reducing life cycle costs.

[0143] After the lease agreement expires, the oil well tubular blocks are collected and inspected. Based on the inspection results, they are categorized into three types: reusable as is, reusable after repair or re-threading, or scrapped and reused. Even if they are reusable, they may be scrapped and reused depending on the needs of the region, size, and grade. In addition, if the steel pipe itself is fine but the threads cannot be reused, it can be re-threaded and reused.

[0144] Furthermore, the lease term may be modified to accommodate situations such as the cancellation or scaling down of a planned project, earlier-than-expected depletion of the oil well, or an extended lifespan of the oil well. It may also be stipulated in advance that the lease agreement will continue even if the contractor changes during the lease term. Additionally, if the tubing remains buried without being removed, the contract may stipulate that the total lease fee be paid in installments as desired by the contractor. Furthermore, if the lease agreement is terminated midway, the termination fee may vary depending on whether or not the oil well tubing is returned.

[0145] Furthermore, if a lease agreement is not permitted, a service agreement and whether or not the used oil well tubular waste will be taken back may be considered, and the lease fee calculated using this information processing device 100 may be used as a reference for a installment contract.

[0146] Thus, when developing a business model for leasing oil well tubular goods, a flexible contract system should be considered to accommodate various cases.

[0147] As described above, the information processing device 100 according to this embodiment can determine the lease fee based on the severity of environmental conditions estimated from environmental data. In this case, the information processing device 100 may determine the lease fee so that it is higher when the partial pressure of carbon dioxide is high than when it is low. The information processing device 100 may also determine the lease fee so that it is higher when the partial pressure of hydrogen sulfide is high than when it is low. The information processing device 100 may also determine the lease fee so that it is higher when the temperature is high than when it is low. The information processing device 100 may also determine the lease fee so that it is higher when the chloride ion concentration is high than when it is low. The information processing device 100 may also determine the lease fee so that it is higher when the water content (water cut) is high than when it is low. In this way, the advantage of CRA over low alloy steel oil well pipes increases when corrosion is more likely, so the lease fee can be increased.

[0148] Furthermore, the information processing device 100 may determine the lease fee so that it is higher when the well is deep than when it is shallow. Also, in offshore locations, the information processing device 100 may determine the lease fee so that it is higher when the well is far from the coast than when it is close to the coast. Furthermore, the information processing device 100 may determine the lease fee so that it is higher when the well pressure is high than when it is low. In this way, when workover costs are high, the advantage of CRA over low alloy steel oil well tubular materials increases, so the lease fee can be increased.

[0149] Furthermore, the lease fee for the information processing device 100 may be determined such that it is higher when the fluctuations in the oil or gas produced from the well are large compared to when they are small. In this way, the lease fee can be increased because the rate of early termination of the lease increases when the fluctuations are large.

[0150] According to the information processing device 100 of this embodiment, the process of determining such lease fees can be automated and executed by the processor 101. Factors indicating the severity of environmental conditions, such as partial pressure of carbon dioxide, partial pressure of hydrogen sulfide, temperature, chloride ion concentration, water content, depth, pressure, distance from the coast, and fluctuations in production volume, constitute a vast amount of multidimensional and correlated data. Therefore, the information processing device 100 can normalize and store this data in a common data structure and calculate the lease fee based on weighting calculations, thereby speeding up the calculation process compared to conventional sequential calculation methods. This reduces the time required to determine lease fees and enables immediate response at the time of lease contract. Furthermore, by integrating and managing environmental data in a common data structure, memory usage efficiency is improved compared to managing each factor individually, and more lease cases can be processed even with the same hardware resources. In addition, by quantifying the severity of environmental conditions and mechanically processing the data, variability due to subjective judgments and input errors can be eliminated, thereby improving the accuracy of corrosion degradation prediction and workover frequency prediction, and enhancing the reliability of lease fee determination. Furthermore, by filtering out factors that do not meet the threshold in the evaluation of the severity of environmental conditions, unnecessary calculations can be omitted, thereby reducing the overall processing load. In other words, the information processing device 100 according to this embodiment is not merely a business rule of setting fees, but rather achieves measurable objective effects such as improved calculation speed, improved memory efficiency, and reduced processing load through improvements in the data processing method, and possesses technical features that contribute to the advancement of information processing technology.

[0151] While the above explanation described pipes (tubes) as the subject of the lease, it is not limited to them. For example, accessories such as fittings, couplings, and crossovers connected to the pipes, as well as equipment made from the same alloy as the pipes (so-called "compound"), may also be included as lease items. In other words, "oil well tubular goods" can be defined as a broad concept that includes at least pipes, and in addition, accessories and other equipment.

[0152] Furthermore, the above explanation described cases where new items (not limited to those produced after receiving an order, but also including unused stock items) or reused items are subject to leasing, but the explanation is not limited to these. For example, leaseback items may also be included as subject to leasing. Leaseback items refer to oil well tubular goods that have been sold once, recovered from the customer, and provided as subject to a lease agreement after undergoing prescribed inspections or maintenance. On the other hand, reused items refer to oil well tubular goods that have been returned upon the expiration of a lease agreement (including early termination), and are similarly provided as subject to a lease agreement after undergoing prescribed inspections or maintenance. In other words, leaseback items are oil well tubular goods with a sales record, while reused items are oil well tubular goods with a lease record. Such leaseback items may also be included as subject to leasing.

[0153] Furthermore, the above explanation described a case where the lease fee is determined on the premise that the oil well tubular waste will be reused after the lease agreement expires, but it is not always the case that the oil well tubular waste will be reused. Depending on the condition of the oil well tubular waste and market conditions, it may be disposed of as scrap after the lease agreement expires. In this case as well, the oil well tubular waste still has value as scrap (scrap value). Therefore, the processor 101 may also take this scrap value into consideration when determining the lease fee.

[0154] <Modification 1> Figure 11 is a diagram showing an example of the schematic configuration of the information processing system 1 according to Modification 1 of this embodiment. The above description described the case in which identification information is pre-printed on the oil well tube during manufacturing. However, at the time of manufacturing, it is often unclear under what environmental conditions the oil well tube will be used in the future. In particular, when oil well tubes are leased to multiple users, the usage conditions are generally not specified to the users until the lease agreement stage, and this uncertainty is even more pronounced.

[0155] Therefore, in Modification 1, after the lease agreement is concluded, the processor 101 determines the processing depth for printing identification information based on environmental data indicating the contracted environmental conditions. Here, the processing depth is the depth of the recess formed on the surface of the pipe P by printing. If the processing is too shallow, the identification information may become unreadable due to abrasion, adhesion of deposits, and plastic deformation, and if the processing is too deep, the mechanical properties may deteriorate due to stress concentration. Therefore, it is desirable to appropriately optimize the processing depth according to the intended environmental conditions of use.

[0156] The information processing system 1 according to Modification 1 further comprises a processing device 60. The processor 101 of the information processing device 100 determines the processing depth for processing the pipe P to print identification information based on environmental data, and outputs a processing command to control the processing device 60 that processes the pipe P based on the processing depth. In this case, the processor 101 may determine the processing depth based on environmental data such that the mechanical properties at the stress concentration point associated with printing the identification information are within a predetermined range.

[0157] For example, if the temperature of the environment in which the oil well pipe is used is high, or if high internal pressure is expected to be applied to the pipe P, residual stress and thermal stress in the pipe P may increase. Therefore, the processor 101 may set the machining (including re-machining) depth relatively shallow from the viewpoint of maintaining mechanical properties within an acceptable range. On the other hand, under environmental conditions with relatively mild temperature and pressure, if the machining is too shallow, identification information may become difficult to see due to abrasion, adhesion of deposits, and plastic deformation. Therefore, the processor 101 may set the machining depth to a certain extent to ensure readability. The information processing device 100 generates a machining command based on such optimization of the machining depth and transmits it to the machining device 60.

[0158] The processing device 60 is a device for printing identification information on the pipe P according to processing commands based on processing instructions transmitted from the information processing device 100. The processing device 60 may include a control unit 61 and an execution unit 62.

[0159] The control unit 61 receives a processing command and generates a processing command to control the execution unit 62 according to the processing conditions, such as the processing depth, included in the command. The execution unit 62 is, for example, composed of a laser stencil device and prints identification information in relief on the surface of the pipe P by irradiating it with laser light through a stencil pattern. In this case, the laser irradiation may be configured so that the irradiation time and laser intensity are controlled based on the processing command output by the control unit 61 to achieve the desired processing depth.

[0160] In the above explanation, the case in which the information processing device 100 directly transmits the processing command to the processing device 60 was described as an example, but it is not limited to this. The information processing device 100 may also transmit the processing command indirectly to the processing device 60 via other devices not shown.

[0161] Furthermore, while the above explanation described the case in which the information processing device 100 transmits a processing command to the processing device 60 as an example, it is not limited to this. The information processing device 100 may also transmit a processing instruction based on the processing command to the processing device 60.

[0162] Thus, the information processing device 100 according to Modification 1 may determine the processing depth for processing the pipe P to print identification information based on environmental data, and output a processing command to control the processing device for processing the pipe based on the processing depth. As a result, the information processing device 100 according to Modification 1 enables appropriate processing according to the usage environment, and can achieve both readability of the identification information and reliability of printing.

[0163] Furthermore, the information processing device 100 according to Modification 1 may determine the processing depth based on environmental data such that the mechanical properties at the stress concentration points associated with printing identification information fall within a predetermined range. As a result, the information processing device 100 according to Modification 1 can suppress mechanical damage to the oil well pipe caused by the printing process, and ensure traceability while maintaining the structural reliability of the oil well pipe.

[0164] Furthermore, the information processing system 1 according to Modification 1 may also include such an information processing device 100 and a processing device 60 that prints identification information on the pipe P according to processing commands based on processing instructions. As a result, the information processing system 1 according to Modification 1 can reliably print identification information at a processing depth optimized according to environmental conditions, thereby realizing oil well pipe management with a balanced approach to identifiability, durability, and structural reliability.

[0165] In Modification 1, the process of determining the processing depth for printing identification information based on environmental data may be performed in conjunction with the process of determining the lease fee based on environmental data, or it may be performed independently. In other words, determining the lease fee is not mandatory when determining the processing depth.

[0166] <Modification 2> Figure 12 shows an example of the processing procedure of the terminal device 20 according to Modification 2 of this embodiment. In the above description, it is assumed that the environmental conditions under which the oil well pipes are used are obtained based on declarations from the user, who is the contractor. However, it is difficult for the leasing company to ascertain the environmental conditions under which the oil well pipes are actually used. In particular, in lease agreements, there may be cases where the environmental conditions declared at the time of the contract differ from the actual usage conditions.

[0167] For example, if the contract declared that the tubular waste would be used in a relatively mild temperature and pressure environment, but it was actually used in a high-temperature and high-pressure environment, this would represent a discrepancy between the declared conditions and the actual usage conditions, which is undesirable. Such discrepancies can lead to inaccurate estimates of the residual value of the tubular waste, making it difficult to set appropriate lease rates when reusing the tubular waste. As a result, there is a possibility of inappropriate pricing.

[0168] Therefore, in Modification 2, the installation location of the oil well pipe is registered based on the position information of the terminal device 20 when it reads the identification information attached to the oil well pipe. However, since oil well pipes are installed underground or underwater where GPS signals cannot reach, it is conceivable that the terminal device 20 cannot determine the absolute position at the installation location. For this reason, the terminal device 20 is configured to use both satellite positioning and inertial navigation. That is, the information processing system 1 according to Modification 2 further includes, in addition to the information processing device 100, a terminal device 20 that calculates the installation location of the oil well pipe based on the position information of its own terminal when it reads the identification information attached to the oil well pipe, and transmits the installation location to the information processing device 100. Note that the terminal device 20 may be the same device as the terminal device 20 used at the time of the lease agreement, or it may be a different device.

[0169] More specifically, in step S310, the terminal device 20 may acquire its absolute position using satellite positioning means such as GPS when it reads identification information on land (not limited to land, but also including on ships and offshore bases) before dropping off the vessel.

[0170] Next, in step S320, the terminal device 20 may continuously measure the displacement from the absolute position using inertial navigation with an acceleration sensor and a gyro sensor during the process of installing the oil well pipe.

[0171] Then, in step S330, when the terminal device 20 reads the identification information again underground or underwater, it may calculate the final installation position of the oil well pipe based on the absolute position determined in step S310 and the displacement measured in step S320.

[0172] Finally, in step S340, when radio waves become available on the ground, the terminal device 20 may transmit the installation location calculated in step S330 to the information processing device 100 in association with the identification information. In response, the information processing device 100 may register the installation location of the oil well pipe in the history database 40.

[0173] Furthermore, various methods generally adopted by those skilled in the art can be used as specific means for reading identification information underground or underwater. For example, if the depth is relatively shallow, the worker may descend to an accessible range and read the identification information using a portable imaging device. If the depth is great, an imaging module (camera unit) that can be suspended by a cable may be inserted, and the identification information may be captured using an imaging device with a light source. In addition, if the oil well pipe is installed underwater or near the seabed, an imaging device for reading identification information may be mounted on a submersible or underwater-traveling unmanned vehicle (ROV: Remotely Operated Vehicle, or AUV: Autonomous Underwater Vehicle), and the unmanned vehicle may be guided to the vicinity of the oil well pipe to read the identification information.

[0174] Thus, the information processing system 1 according to Modification 2 may include, in addition to the information processing device 100, a terminal device 20 that calculates the installation location of the oil well pipe based on the location information of the terminal when it reads the identification information, and transmits the installation location to the information processing device 100. As a result, the information processing system 1 according to Modification 2 can obtain location information of where the oil well pipe is actually installed, thereby enabling highly reliable reuse decisions and asset management based on the installation environment.

[0175] Furthermore, when the terminal device 20 reads the identification information, it may determine its absolute position, measure the displacement from the absolute position using inertial navigation during the process of installing the oil well pipe, and calculate the installation position of the oil well pipe based on the absolute position and displacement. As a result, according to the information processing system 1 of modified example 2, it is possible to acquire and record the final installation position of the oil well pipe with high accuracy even in environments where satellite positioning is difficult, such as underground or underwater, thus reliably leaving installation evidence that will be useful for later verification of usage history and confirmation of the appropriateness of lease agreements.

[0176] In Modification 2, the process of calculating and transmitting the installation location of the oil well pipe may be performed in conjunction with the process of determining the lease fee based on environmental data, or it may be performed independently. In other words, determining the lease fee is not required when calculating and transmitting the installation location.

[0177] Furthermore, this disclosure may also provide a terminal device 20 suitable for information processing that acquires fee information and allows viewing of historical information related to the leasing of oil well pipes.

[0178] Figure 13 shows an example of the functional configuration of the terminal device 20 according to this embodiment. The terminal device 20 includes a reception unit 310, a creation unit 320, a transmission unit 330, an acquisition unit 340, a display unit 350, and a recording unit 360.

[0179] The reception unit 310 is a functional unit that receives input from the user of environmental data indicating the environmental conditions under which the oil well pipe is used. For example, temperature, pressure, CO2, etc. are displayed on the operation screen of the terminal device 20. ２ Partial pressure, H ２ The system includes fields for inputting S-partial pressure, depth, and region, allowing it to accept environmental conditions entered by the user.

[0180] The creation unit 320 is a functional unit that creates a fee information request requesting lease fee information regarding the lease fee for oil well tubular goods based on environmental data received from the user. This fee information request may include information such as the input environmental data, desired period, desired size or grade, etc.

[0181] The transmission unit 330 is a functional unit that transmits the environmental data received by the reception unit 310 and the fee information request created by the creation unit 320 to the information processing device 100 (for example, the server device 10) via the network. Based on the received request, the information processing device 100 identifies the oil well tubular goods to be leased and determines the lease fee.

[0182] The acquisition unit 340 is a functional unit that acquires lease fee information, including the lease fee determined by the information processing device 100, in response to a transmitted request. The acquired lease fee information may be the fee for a single oil well tubular block, or it may be in the form of a price list corresponding to multiple candidates.

[0183] The display unit 350 is a functional unit that displays lease fee information acquired by the acquisition unit 340. For example, it may display the lease fee, contract terms, and specifications of the oil well tubular goods to be leased in a list format. The display unit 350 may also display buttons (for example, "Contract Application" or "Request Quote" buttons) that allow the user to select whether or not to proceed with the lease agreement.

[0184] The recording unit 360 is a functional unit that records user identification information for identifying a user. For example, it may store a user ID, authentication token, or subscriber number in its storage area. This user identification information is used for authentication and access control in contract processing and history data viewing processing, as will be described later.

[0185] With this configuration, the terminal device 20 can not only easily acquire and display oil well pipe lease fee information in response to user operations, but can also securely execute contract procedures and history viewing requests using user identification information. In particular, when the contract button displayed on the display unit 350 is pressed, the transmission unit 330 transmits the button selection result to the information processing device 100 in association with the user identification information recorded in the recording unit 360, thereby enabling automatic recording of the contract progress history on the server side.

[0186] Furthermore, the terminal device 20 may also respond to user requests to view historical data. In this case, the creation unit 320 creates a viewing request to view the historical data of the leased oil well tubular goods in response to the user's request. The transmission unit 330 transmits the viewing request created by the creation unit 320 to the information processing device 100, associating it with user identification information.

[0187] When the information processing device 100 receives this viewing request, it returns the corresponding history data to the terminal device 20 with viewing restrictions applied according to the user identification information. For example, if the past user is the same user, the entire history is made viewable; otherwise, access control is performed such as masking subscriber information before providing the data. With this configuration, even if the link destination is shared with a third party, security is ensured because only data with viewing restrictions will be displayed unless the user passes the authentication process based on the user identification information.

[0188] As described above, the terminal device 20 is equipped with the function to perform a series of processes from inputting environmental data to acquiring and displaying lease fee information, expressing intent to contract, and requesting to view historical data, and can communicate with the server device 10 safely and efficiently through association with user identification information.

[0189] In the embodiments described above, the term "processor" refers to a broad type of processor, including general-purpose processors (e.g., CPUs) and dedicated processors (e.g., GPUs: Graphics Processing Units, ASICs: Application Specific Integrated Circuits, FPGAs: Field Programmable Gate Arrays, programmable logic devices, etc.).

[0190] Furthermore, the processor operation in the above-described embodiment may not be performed by a single processor, but may be performed by multiple processors located in physically separate locations working together. Also, the order of each processor operation is not limited to the order described in the above-described embodiment, but may be changed as appropriate.

[0191] Furthermore, although the information processing device 100 in this embodiment is described as being composed of a single device, it may also be composed of multiple devices.

[0192] Furthermore, the processing performed by the information processing device 100 according to the above embodiment may be performed by software, by hardware, or by a combination of both. In addition, the processing performed by each part of the information processing device 100 may be stored as a program on a storage medium and distributed.

[0193] Furthermore, this disclosure is not limited to the foregoing, and it is of course possible to implement it in various modified forms without departing from its intent.

[0194] Furthermore, the disclosure of Japanese Patent Application No. 2024-231164 is incorporated herein by reference in its entirety. In addition, all documents, patent applications, and technical standards described herein are incorporated herein by reference to the same extent as if each individual document, patent application, and technical standard were specifically and individually noted to be incorporated by reference.
