Description

TECHNICAL FIELD

[0001] The present disclosure relates to well interventions, and more specifically, to an automated well intervention plan generator. BACKGROUND

[0002] In the field of oil and gas exploration, efficient extraction of hydrocarbon resources is critical to maximizing production and minimizing costs. As geographic locations for extracting hydrocarbons have increasingly developed, the proportion of production from mature hydrocarbon production has also increased. Thus, maximizing the productivity and efficiency of existing wells has become increasingly important.

[0003] Well intervention is one method of increasing productivity. At some point in the life of all oil and gas wells, components will need maintenance, repair, or replacement. At these times, operators can turn to intervention specialists. Interventions are divided into two broad categories: light or heavy intervention. During light intervention, technicians run tools or sensors into the field well while containing pressure at the surface. In heavy intervention, rig crews can stop production at the formation before making major equipment changes.

[0004] Well service personnel typically use wireline, slickline, or coiled tubing for light intervention. These systems allow operators to minimize the potential for well plugging. Operators also command light intervention to change or adjust downhole equipment, such as valves or pumps, or to collect downhole pressure, temperature, and flow data. Heavy intervention, also known as workover, can require rig crews to remove wellheads and other pressure barriers from the well to allow full access to the wellbore. These operations can require a rig to remove and reinstall wellheads and completion equipment. Heavy intervention can be used to replace components that cannot be retrieved by light intervention, such as tubing strings and pumps. Some heavy interventions are performed to plug and abandon original production zones to reconfigure the well to produce from secondary zones; these operations are known as re-completions.

[0005] Software can be used to plan well interventions. For example, well intervention software can be used to help select wells to intervene on, to determine intervention methods that will yield the best results, and / or to generate detailed work plans for well interventions. Using such well intervention software can increase the likelihood of successful well interventions and maximize the productivity of wells. Well intervention software can provide an interactive tool for intervention planning. Intervention plans can include an operational plan, inflow simulation, estimated duration, estimated probability of success, pre-intervention production, estimated post-intervention production, net present value (NPV), a list of equipment and personnel to perform intervention operations, and an indication of price. The operational plan can include a sequence of operations using intervention techniques, including primary and contingency workflows. A user can use well intervention software to develop an operational plan. The operational plan can be a starting point for inflow simulation and indication of price. One example software is Intervention Advisor (IA) provided by Schlumberger Limited, Houston, Texas.

[0006] With current well intervention software, a user manually builds intervention plans using interactive well intervention software. Such manual planning can be time consuming, can require specialized knowledge of the user, and is subject to human error.

[0007] There is a need for further improvements in well intervention planning. SUMMARY

[0031] The present disclosure provides techniques, methods, systems, apparatuses, and computer readable media for automated intervention planning.

[0032] According to certain aspects, a well intervention can involve various intervention operations associated with various intervention techniques. In some aspects, the various intervention operations and techniques can be performed according to a specified sequence. The sequence of well intervention techniques and operations can be referred to as an intervention main path. The intervention main path can be performed to address one or more specified well symptoms. The well in which the intervention is being performed can be associated with one or more well conditions, such as completion, well trajectory, and well operational data. One or more objectives for the well intervention can be specified. In some aspects, an emergency path can be followed when the main path is unsuccessful.

[0033] According to certain aspects, historical well intervention information can be collected. The historical well intervention information can include information about previous well interventions and can be collected from multiple users of a well intervention system. The collected historical intervention information can be used to maintain statistics about well interventions. For example, intervention main paths and emergency paths can be associated with respective intervention objectives, well conditions, counts of the number of times the path was used (e.g., successfully), probabilities of success, costs, and / or durations. Well conditions can include completion and well trajectory information. Well condition information can include well survey information for the well, wellbore conditions (e.g., temperature, pressure, presence or amount of corrosive gases such as hydrogen sulfide and carbon dioxide), type of completion, size of completion, weight of completion, and / or information about downhole components such as casings, packers, artificial lift equipment, subsurface safety valves (SSSVs), and / or other equipment or well condition information such as high production well information, injection well information. The historical information and statistics can be used for automated well intervention plan generation.

[0034] ​In some respects, an automated well intervention plan generation system can receive input from a user regarding well interventions. This system can match the user-inputted information with historical data related to well interventions to generate a well intervention plan to recommend to the user. In other respects, the user-inputted information is sent to a template service to request predefined templates from a template database created by domain experts, and the information is also sent to a plan generator that creates a plan based on historical information and statistics.

[0035] In some aspects, the system selects a well intervention plan from the database that most closely matches the user-inputted intervention objectives and well conditions. In other aspects, the system selects a well intervention plan from the database based on one or more user preferences input by the user. In still others, the system identifies multiple plans in the database that are equally matched to the user-inputted intervention objectives and well conditions. In this case, the system can select a well intervention plan from multiple plans based on criteria such as highest count, shortest duration, lowest cost, and / or other criteria. In some aspects, the system also selects an emergency path based on historical and statistical information.

[0036] In some respects, physical models can be used to model wells to help select well intervention plans for them. In other respects, physical models can be used to select a subset of well intervention plans (e.g., by filtering one or more well intervention plans from a database based on modeling), and the system can then select well intervention plans from the subset based on the matching of intervention objectives and well conditions and / or based on criteria.

[0037] In some respects, the system also generates well intervention plans based on information about the available equipment for performing well intervention operations. Equipment information may include equipment procurement information, equipment inventory information, and / or equipment maintenance information. In some respects, the type or effectiveness of well interventions, well intervention techniques, and / or well intervention operations may be limited based on the available equipment. In some respects, equipment information may be used to select a subset of well intervention plans from a database, and then well intervention plans may be selected from the subset of well intervention plans based on historical statistical information associated with that subset.

[0038] The following description includes embodiments of the best mode currently contemplated for practice of the described implementations. This description should not be considered limiting, but rather made solely for the purpose of describing the general principles of the implementations. The scope of the described implementations should be determined with reference to the published claims.

[0039] Example Automated Well Intervention Plan Generator

[0040] Figure 1 An example automated well intervention plan generator system 100 is described.

[0041] As shown in the figure, user 105 of the automated well intervention plan generator system 100 can input information to the intervention plan generator main service 115 via user interface 110. For example, user 105 can input information used by the automated well intervention plan generator system 100 to automatically generate a well intervention plan. Figure 1 As shown, and as this article relates to Figures 2-11 In more detail, the information input by user 105 to intervention plan generator main service 115 via user interface 110 may include well selection information, intervention objectives, well symptoms, well conditions, report configuration and / or other information.

[0042] Figures 2-13 An example display of the user interface 110, which allows user 105 to operate the automated well intervention plan generator system 100, is shown. However, it should be understood that... Figures 2-13 The example shown is merely an illustrative example of user interface 110. In some respects, Figures 2-13 The display includes selectable options. These selectable options can be in the form of buttons. When user 105 selects (e.g., presses) one of the buttons, user interface 110 can display a new screen, drop-down menu, or pop-up window with information associated with the selectable option. Furthermore, while the illustrative example provides selectable options, in some cases, user 105 can directly input information into user interface 110, for example, by manually entering or typing information instead of selecting the provided option. Additionally, while some information is described as information entered in fields, it should be understood that in other examples, this information can be provided as a selectable option. Furthermore, although... Figures 2-13 Various user inputs and choices are illustrated, but in some respects, one or more of these inputs can be automated. For example, information about well conditions can be collected by sensors and provided to the system, and well selection and intervention targets can be automatically determined, selected, and / or defined by the system (i.e., with no user input and / or minimal user input).

[0043] Figure 2 An example main display 200 of the user interface 110 is depicted. As shown, the main display 200 may include selectable options for well 205 and selectable options for intervention 210.

[0044] In some respects, the information input by user 105 includes the selection of wells for intervention. For example, user 105 can select the selection option for well 205, thereby providing user 105 with a list of one or more wells that can be selected for intervention. Figure 3An example well selection display 300 of the user interface 110 is depicted. As shown, the well selection display 300 may include a list of wells. Wells may be associated with well identifiers (IDs). The list of wells may be selectable. For example, the list may include selectable options for well ID 1 305, well ID 2 310, ... and so on, for one or more wells, up to the selectable options for well ID N.

[0045] After selecting a well, user 105 can begin entering information that enables the automatic well intervention plan generator system 100 to automatically generate a well intervention plan for the selected well. In the illustrative example, user 105 can select optional options for the well intervention plan 210. Figure 4 An example well intervention display 400 of the user interface 110 is depicted. As shown, the well selection display 400 may include selectable options for entering plan overview information 405, selectable options for entering pre-intervention information 410, and selectable options for generating one or more well intervention plans 415 for the selected well.

[0046] In some respects, the program overview information includes intervention objectives. In an illustrative example, in response to user 105 selecting optional options for program overview 405, a list of optional options for the market and / or environment may be provided to user 105. Figure 5 The example plan overview of user interface 110 is shown in Figure 500. In one example, such as... Figure 5 As shown, user 105 may be provided with selectable options for market and / or environment Y, including selectable options for market and / or environment 1 505, market and / or environment 2 510, etc., up to market and / or environment Y 515. Market can be a geographic region, country, and / or other market options. Environment can include whether the well is onshore or offshore, such as deepwater, offshore, remote, platform, high-end onshore operations, high-capacity onshore operations, and / or other environments.

[0047] In some aspects, the program overview information includes well symptoms to be addressed by well intervention. In an illustrative example, in response to user 105 selecting an optional option for program overview 405, a list of optional options for the well symptoms can be provided to user 105. Alternatively, a list of optional options for the well symptoms can be provided after user 105 selects a market and / or environment. Alternatively, a list of optional options for the market and / or environment can be provided after user 105 selects a well symptom. Alternatively, the list of optional options for the well symptoms can be provided together with the selection options for the market and / or environment. Figure 6 Another example plan overview display 600 depicts the user interface 110. In one example, such as Figure 6As shown, user 105 can be provided with selectable options for well symptoms Z, including symptom 1 605, symptom 2 610, and so on up to symptom Z 615. Well symptoms can include a variety of types. Some non-limiting illustrative examples include increased skin coverage, ineffective casing, increased water cut, decreased flow rate, annular pressure buildup, apparent asphaltene deposition, reduced caliper logging, camera evidence of blockage, ineffective fittings, inability to rig, decreased production, deposits in surface equipment, high dogleg severity, and changes in downhole pressure.

[0048] In some aspects, the program overview information includes the intervention type. In an illustrative example, in response to user 105 selecting an optional option for program overview 405, a list of optional options for the well intervention type can be provided to user 105. Alternatively, a list of optional options for the well intervention type can be provided after user 105 selects a market and / or environment and / or selects a well symptom. Alternatively, a list of optional options for the market and / or environment and / or well symptom can be provided after user 105 selects a well intervention type. Alternatively, the list of optional options for the well intervention type can be provided together with selection options for (one or more) market and / or environment and / or well symptom(s). Figure 7 Another example plan overview of user interface 110 is shown in display 700. In one example, such as Figure 7 As shown, user 105 can be provided with selectable options for well intervention types L, including intervention type 1705, intervention type 2 710, and so on, up to intervention type 1 715. Well intervention types can include a variety of well intervention types. Some non-limiting illustrative examples include sand consolidation, sand ingress evaluation, sand control, sand screen repair, barrier diagnosis, tubing buckling, tubing deformation, cement evaluation, in-well debris, and top debris of completion fittings.

[0049] In some respects, pre-intervention information includes well completion information, trajectory information, and / or operational data. Figure 8 An example pre-intervention display 800 of the user interface 110 is depicted. In the illustrative example, the user 105 can select optional options for pre-intervention information 410, and can be provided with optional options for well completion information 805, optional options for trajectory information 810, and optional options for operational data information 815.

[0050] In some aspects, completion information includes completion information about the selected well. In some aspects, completion information includes downhole equipment information, manpower information, fluid information, and / or fittings information about the selected well. In some aspects, in response to user 105 selecting selectable options for completion information 805, user 105 may be provided with a list of selectable options for inputting downhole equipment information, manpower information, fluid information, and / or fittings information about the selected well. In an illustrative example, in response to user 105 selecting selectable options for completion information 805 (or additionally, in response to selecting selectable sub-options for fittings information), user 105 may be provided with a set of fields for inputting completion information (e.g., casing information, piping information, and / or perforation information). Figure 9 Another example of the user interface 110 before intervention is depicted as 900. In one example, such as Figure 9 As shown, user 105 may be provided with fields for inputting casing information 905, fields for inputting tubing information 910, and / or fields for inputting perforation information 915. Fields for inputting casing information 905 may include fields for inputting the start and end measurement depths (MD) of the casing, fields for inputting the outer diameter (OD) of the casing, fields for inputting the weight of the casing, and / or fields for inputting the inner diameter (ID) of the casing. Fields for inputting tubing information 910 may include fields for inputting the start and end measurement depths of the tubing, fields for inputting the outer diameter of the tubing, fields for inputting the weight of the tubing, and / or fields for inputting the inner diameter of the tubing. In some aspects, fields may include fields for inputting casing thickness and / or tubing thickness. For each perforation, fields for inputting perforation information 915 may include fields for inputting the perforation name, fields for inputting the top measurement depth, and fields for inputting the bottom measurement depth. Completion information may also include one or more fields for inputting other completion information (e.g., various completion information). In some respects, completion information includes information indicating whether the well is a cased well or an open hole well. In other respects, it may also display visualizations of the completion (e.g., graphic images or models).

[0051] In some respects, well trajectory information includes trajectory information about the selected well. In an illustrative example, in response to user 105 selecting an optional option for well trajectory information 810, user 105 may be provided with a set of fields for inputting well trajectory information, such as for one or more measurement points, measurement depth, well angle, azimuth, and true vertical depth (TVD). Figure 10 Another example of the user interface 110 is depicted, showing a pre-intervention display 1000. In illustrative examples, such as... Figure 10As shown, the system can provide user 105 with fields for inputting a measurement depth 1005, an angle 1010 at the measurement depth, an azimuth angle 1015 at the measurement depth, and a TVD at the measurement depth. In some aspects, the well trajectory information includes information indicating whether the well is a vertical, horizontal, or deviated well. In some aspects, a visualization of the well trajectory (e.g., a graphic image or model) can also be displayed.

[0052] In some aspects, well operation information includes operational data about the selected well. In some aspects, operational data information includes pressure, temperature, and / or fluid density information about the selected well. In some aspects, in response to user 105 selecting selectable options for well operation data information 815, a set of fields for inputting well operation data information can be provided to user 105. Figure 11 Another example of a pre-intervention display 1100 is depicted for the user interface 110. In one example, such as Figure 11 As shown, user 105 may be provided with fields 1105 for inputting pressure information, 1110 for inputting temperature information, and / or 1115 for inputting fluid density information. In some aspects, well operation information includes fields for inputting the minimum limits of the well, fields for inputting the total depth (TD), and / or fields for inputting the seafloor depth. In some aspects, the field for inputting pressure information 1105 includes the maximum pressure at the total depth. In some aspects, the field for inputting temperature information 1110 includes fields for inputting the maximum temperature at the total depth, fields for inputting the surface temperature, and / or fields for inputting the seafloor temperature. In some aspects, the field 1115 for inputting fluid density information includes fields for inputting the fluid in the well and / or fields for inputting the fluid density of the fluid. In some aspects, well operation information includes fields for indicating the presence of acidic gas and fields for indicating the concentration of acidic gas.

[0053] In some systems, the intervention plan for the selected well is manually created by user 105. For example, in some systems, in response to selecting optional options for well intervention 415, user 105 may need to input each intervention technique (e.g., for assessment, perforation, development, cement assessment, ultrasonic logging tools, plugging, grinding, cleaning, etc.) and associated interventions, symptoms, and tools to manually generate an intervention plan. (The following will discuss...) Figure 1 As discussed in more detail with respect to various aspects of this disclosure, as shown in Figures 14-16, the automatic well intervention plan generator system 100 can automatically generate well interventions based on intervention objectives and well conditions.

[0054] The well intervention plan can provide user 105 with information such as the primary path, one or more contingency paths, decision tree information, intervention duration, success probability, pricing information, data visualization, and reporting. In the example shown, in response to user 105 selecting selectable options for well intervention 415, a well plan can be automatically generated, and a list of selectable options can be provided to user 105. Figure 12 Example intervention display 1200 depicts user interface 110. (e.g.) Figure 12 As shown, the intervention display 1200 includes selectable options 1205 for decision tree information, selectable options 1210 for pricing information, selectable options 1215 for data visualization, and / or selectable options 1220 for reporting. In response to user 105 selecting an option for pricing information 1210, pricing information associated with the cost of implementing the well intervention plan can be provided to user 105. The selectable options for reporting 1220 allow user 105 to select one or more options for configuring reports for the well intervention plan.

[0055] Figure 13 A well intervention plan report display 1300 is shown for a user interface 110 used for an example well intervention plan report. As shown, the well intervention plan report can display intervention objectives 1305, path information 1310, and inflow information 1345. Path information 1310 can include one or more operations 1315. For each operation 1315, path information 1310 can include associated technology 1320, estimated cost 1325 of operation 1315, estimated duration 1330 of operation 1315, estimated probability of success 1335 of operation 1315, and / or exit point 1340 of operation 1315. Exit point 1340 can indicate the implementation cost and / or duration at which the operation can be aborted. In some cases, an emergency path can be followed when the operation is aborted. Inflow information 1345 can include estimated, predicted, or simulated inflow values ​​of one or more fluids associated with the well. Figure 13 As shown, inflow information 1345 may include information on water inflow 1350, oil inflow 1355, and / or gas inflow 1360. Inflow information allows for the assessment of inflow following a well intervention, even without a planned intervention. In some respects, the implementation or non-implementation of a well intervention plan can be based at least in part on differences in inflow.

[0056] As described above, the automated well intervention plan generator system 100 automatically generates a well intervention plan for a selected well based on target and well condition information input by the user 105 via the user interface 110 to the intervention plan generator main service 115. In some aspects, the user 105 can also input one or more user preferences for intervention plan generation. (Return to Reference) Figure 1The intervention plan generator master service 115 can feed user input to the intervention plan template service 120 to request one or more intervention plan templates. The intervention plan template service 120 of the automated well intervention plan generator system 100 can maintain (e.g., locally or remotely accessed) a database of well intervention plans. In some aspects, the well intervention plans in the database include well intervention plans predefined by domain experts. In some aspects, well intervention plans can be selected from the intervention plan template service based on a match between well conditions and intervention objectives and / or criteria.

[0057] The intervention plan generator master service 115 can also feed user input to the intervention plan generator 125 to request one or more intervention plans. In some aspects, the intervention plan generator 125 uses historical information and / or statistics associated with well intervention plans to generate well intervention plans. In some aspects, historical information on well intervention plans is collected among many users of the intervention plan generator master service 115, who can be associated with many different wells. In some aspects, the historical information includes operational data, such as data collected by one or more logging tools. In some aspects, the well intervention plan template service associates well intervention plans in the well intervention plan database with statistics, intervention objectives, operational data, and / or well conditions.

[0058] Depending on certain aspects, historical information about well intervention plans is correlated with other information, such as intervention objectives and / or well conditions (e.g., completion information, trajectory, and / or operational data). Additionally, other criteria can be correlated with historical information, such as duration, cost, counts (number of times the plan was used or successfully used), and / or user preferences. Based on these correlations, the current intervention plan can be generated.

[0059] In some respects, the intervention plan generator master service 115 uses machine learning models to generate well intervention plans based on historical information.

[0060] In some respects, the intervention plan generator master service 115 outputs two well intervention plans to user 105. The system can provide users with recommended expert-created well intervention plans from the intervention plan template service, based on statistical information associated with a database of well information plans collected across users and wells by the intervention plan generator master service 115, and also provide users with recommended well intervention plans from the intervention plan generator.

[0061] Figures 14A-14BAn illustrative example of collected historical well intervention plan information and related statistics is provided. It should be understood that historical well intervention plan information may include fewer or more plans than those shown. Furthermore, plans may include historical well intervention plan information associated with many different objectives, different numbers of objectives, many different main paths, different numbers of main paths, many different contingency paths, different numbers of contingency paths, many different well conditions, and / or many different numbers of well conditions. Figures 14A-14B The supplements or alternatives to those shown.

[0062] Figure 14A The example depicts historical well intervention plan information collected. (For example...) Figure 14A As shown, the collectable historical well intervention plan information includes multiple well intervention plans—Plan 1, Plan 2, Plan 3, and Plan 4. In the illustrative example, the well intervention plans are associated with intervention objectives Oa, Ob, and Oc. In the illustrative example, well intervention plan 1 includes a “main path” using techniques A, B, and C. For example, technique A may be associated with the first intervention operation in the well intervention plan (e.g., such as operation 1315), technique B may be associated with the second intervention operation, and technique C may be associated with the third intervention operation. Figure 14A As shown, Schemes 2 and 3 also use the main paths A, B, and C. Furthermore... Figure 14A As shown, Plan 2 includes a contingency plan, where Technology D serves as a backup to Technology B. Technology D can be associated with a fourth intervention operation. The contingency plan can be followed when the primary path fails, such as when a technology point reaches the exit point based on actual cost and / or duration. Figure 14A As shown, Plan 3 utilizes Technology D and additionally uses Technology E as a second contingency. Technology E can be associated with the fifth intervention. Figure 14A As shown, Plan 4 uses different main pathways with techniques F, G, and H. Technique F can be associated with the sixth intervention, technique G can be associated with the seventh intervention, and technique H can be associated with the eighth intervention.

[0063] Figure 14B Depicting Figure 14AExample statistical associations of collected historical well intervention plan information. As shown in the figure, the main paths A, B, and C used in plans 1, 2, and 3 can have a first assigned path ID (path ID 1), and the main paths F, G, and H used by plan 4 can have a second assigned path ID (path ID 2). Both path ID 1 and path ID 2 are associated with the set of targets Oa, Ob, and Oc. Path ID 1 is associated with the well conditions "vertical" and "cased well," and path ID 2 is associated with the well conditions "vertical" and "open hole well." Path ID 1 is also associated with count 3, indicating that the main path of path ID 1 was used in three intervention plans, and path ID 2 is associated with count 1, indicating that the main path of path ID 2 was used only once (for plan 4).

[0064] In addition, a first emergency path ID and a second emergency path ID can be assigned. The first emergency path ID is associated with technology D, the emergency location {B,1} indicating that technology D is an emergency response to technology B, and count 2. The second emergency path ID is associated with technology E, the emergency location {B,1}, and count 1.

[0065] Historical information and statistics can be used to provide well intervention plans (and / or templates) to the intervention plan generator master service 115 based on the objectives and well conditions input by user 105. For example, well intervention plans associated with the objectives and well conditions that most closely match those input by user 105 can be selected from the database. In some aspects, in the case of multiple well intervention plan matches, the well intervention plan with the highest count among equally matched well intervention plans can be selected. In some aspects, well intervention plans can be further selected based on user preferences configured for selecting well intervention plan templates from the database. In some aspects, well intervention plans can be further selected based on cost, operational risk (e.g., probability of success), and duration. In some aspects, selection can be based on weights and / or thresholds, thereby balancing the level of matching objectives and well conditions with user preferences, cost, risk, and / or duration.

[0066] Return to reference Figures 14A-14BIn the example shown, for a well intervention with a target Oa and well conditions "vertical well" and "cased well", the automated well intervention planning system 100 can search the data and find that both main path ID 1 and main path ID 2 match the target, and the well condition is a complete match for main path ID 1, but only a partial match for main path ID 2 (e.g., main path ID 2 is used for "open hole well"). In this case, the automated well intervention plan generator system 100 can select main path ID 1 for the well intervention plan. Alternatively, if main path ID 2 is also used for "cased well", then both main path ID 1 and main path ID 2 will be a complete match. In this case, the automated well intervention plan generator system 100 can select main path ID 1 based on the main path ID 1 with the higher count. In some aspects, the selection can be based on other criteria, such as user preferences for the well intervention associated with main path ID 1 and main path ID 2, the associated duration, and / or the associated cost.

[0067] In some aspects, for emergency path recommendation, the automated well intervention plan generator system 100 can select emergency paths based on standards. For example, refer again... Figures 14A-14B In the example shown, for technology B, the automated well intervention plan generator system 100 can recommend emergency path D based on the emergency path D with the highest count.

[0068] In some respects, historical information from previous well intervention programs can be preprocessed. For example, missing values ​​can be added (e.g., estimated), outliers can be removed, units can be standardized, and / or the data can be categorized.

[0069] In some respects, a well intervention is considered successful if it achieves the input objectives. In other respects, user 105 can input feedback on the well intervention plan, indicating that the plan was successful.
