[0034] Other features and advantages of the invention will appear upon reading the following description, provided solely as an example and done in reference to the appended drawings, in which:

[0035] - Figure 1 is a schematic view of an example of a hydrocarbon extraction or injection site, - Figure 2 is a schematic view of an example of steps of a method according to the invention,

[0039] An example of a hydrocarbon extraction or injection site 10, more particularly here of an extraction site, is represented on figure 1.

[0040] Said example is very simplified, such as to illustrate the purpose of the description. However, the invention is not limited to such a site and is adaptable to any desired hydrocarbon extraction or injection site.

[0041] The site 10 comprises at least one well 12 and a surface facility 14.

[0042] The at least one well 12 is connected to a hydrocarbon reservoir 16.

[0043] The surface facility 14 is connected to the at least one well 12, and thus to the reservoir 16.

[0044] Different fluids are extracted from the at least one well 12, in particular here gas, oil and water.

[0045] The surface facility 14 comprises a plurality of surface equipment.

[0046] Each surface equipment is connected to one or a plurality of other surface equipment.

[0047] The surface equipment are arranged in a surface configuration.

[0048] The surface equipment are connected to the well or wells 12 and to each other, according to different fluidic and energy flows.

[0049] In the represented embodiment, the surface facility 14 comprises at least one operation line per extracted fluid, here at least one gas line 18, at least one oil line 20 and at least one water line 22.

[0050] The gas line 18, for example, comprises at least one compressor 24 for compressing the gas.

[0051] The gas line 18 further comprises a network interface 26 for directing the gas from the well, for example to the at least one compressor 24.

[0052] Downstream the network interface 26, for example downstream the at least one compressor 24, at least part of the produced gas is sent to at least one turbine, preferably a plurality of turbines 28 arranged in parallel, for producing electricity from said gas.

[0053] The electricity is then sent to an energy source 30. Here, downstream the network interface 26, for example downstream the at least one compressor 24, the rest of the compressed gas may be sent to at least one gas flare 32 for flaring said gas.

[0054] The surface facility 14 further comprises a heat producer 34, such as a furnace.

[0055] The oil line 20, for example, comprises a heater 36].

[0056] Said heater 36 is provided with heat from the heat producer 34.

[0057] The oil line 20 further comprises at least one pump 38, for pumping the oil along the oil line.

[0058] At least one pump of the at least one pump is provided downstream the oil line 20 before its distribution.

[0059] Oil is provided from the oil line 20.

[0060] The water line 22 comprises at least one pump 40 for pumping the water along the water line 22, in particular at the beginning of the water line 20 before any other equipment.

[0061] The water line 22 further comprises at least one heater 42.

[0062] Said heater 42 is provided with heat from the heat producer 34.

[0063] In the example, the water line 22 divides between a plurality of sublines after a pump and before the at least one heater. Each subline comprises at least one heater.

[0064] The water line 22, here particularly each subline, comprises at least one pump 42 for pumping the water and providing the water downstream of said line, in particular here downstream the at least one heater, here for said sublines.

[0065] Each compressor 24 and each pump 38, 40, 44 is provided with electricity by the energy source 30.

[0066] The energy source 30 is connected to an outside electrical network 46.

[0067] In one embodiment, the site 10 comprises at least one equipment for producing renewable energy 48.

[0068] Said equipment for producing renewable energy 48 is connected to the energy source 30.

[0069] The energy source 30 is adapted to distribute the energy from incoming sources, such as the outside electrical network 46, the turbines 28, the equipment 48, to demanding equipment, comprising the compressor(s) and pumps.

[0070] As mentioned previously, the previously described example of a site is only given for illustrative reasons.

[0071] The site may be completely different.

[0072] The site of figure 1 is used to give an example of application of a method for configuring a hydrocarbon extraction or injection site comprising at least one well and a surface facility, the surface facility being connected to the at least one well and one reservoir.

[0073] In an alternative embodiment, the site is a site for carbon capture and storage within the reservoir in which said carbon dioxide is injected into the reservoir through the well(s).

[0074] The method represented in figure 2 comprises the following steps:

[0075] - receiving 100 operating information on a plurality of surface equipment for at least one surface configuration of the surface facility connected to the at least one well and one reservoir,

[0076] - generating 102 a model of the at least one surface configuration from the received operating information, and

[0077] - calculating 104 at least one production and / or injection profile and associated Green House Gas emissions associated with the or each surface configuration in the corresponding model, for the or each production and / or injection profile.

[0078] The operating information comprises the number, the nature and the arrangement of the surface equipment for said surface configuration.

[0079] Further, each surface equipment is associated to a performance curve, the performance curve linking the service provided by said equipment to the associated power and / or heat need and therefore Green House Gas emissions.

[0080] The performance curve is, for example, built from real historical data and / or provided data, for example provided by the constructor of said surface equipment, and / or predefined laws, in particular including physics laws.

[0081] The operating information comprises the performance curve of each surface equipment of the surface configuration.

[0082] In the example of figure 1 , the operating information would, for example, comprise the nature of each type of surface equipment (pump, compressor, heater...), the number of each type of equipment and how they are connected to one another, and here further the performance curve of each surface equipment.

[0083] Different equipment of the same type may have different capacity to produce a corresponding subservice. For example, pumps may have different volumes or intervals of pressure, or heaters may have different intervals of operating temperature or volumes.

[0084] Furthermore, different equipment of the same type, and if applicable with the same capacity, may have the same performance curve, in particular if based on data provided by the constructor, but may also have different performance curves.

[0085] For the or each surface configuration, the surface equipment are connected to the well or wells and to each other in the arrangement of the operating information, according to different fluidic and energy flows. The operating information are, for example, received via a Python script.

[0086] More particularly, in one embodiment, the method, more particularly the receiving step, comprises displaying a human-machine interface.

[0087] An example of a human-machine interface 200 is represented on figure 3.

[0088] The human-machine interface 200 displays a representation of potential equipment 202 of the surface facility.

[0089] The human-machine interface 200 comprises a sub-interface 204 for building the at least one surface configuration from the potential equipment and potential connections within the surface facility.

[0090] More particularly, the human machine interface 200 enables clicking on the representation of potential equipment 202 one equipment at a time, and positioning the clicked-on potential equipment in said sub-interface 204, according here to a click-drag- drop technique, in order to build the at least one surface configuration.

[0091] The human machine interface further allows creating connections between the equipment positioned in the sub-interface 204.

[0092] For example, for creating a connection between two equipment in the human-machine interface 200, one clicks on a first of the equipment, here providing the subservice or fluid delivered by said connection, the human-machine generating a line from said click, and drags the line to the second of the equipment, here receiving the subservice or fluid.

[0093] The nature of the connection may be specified by a user of the interface or may be directly derived by the human-machine interface from the types of the equipment that are connected.

[0094] Alternatively, the potential connections are created in the human-machine interface similarly to the potential equipment, with a representation of potential connections, that allows clicking, dragging and dropping the desired connection, and linking said connection to the associated equipment.

[0095] The human-machine interface thus allows building a surface configuration representation, including the different surface equipment and their arrangement within the configuration.

[0096] In one embodiment, for each potential equipment, the human-machine interface 200 allows selecting a corresponding performance curve.

[0097] More particularly, in the case where similar types of equipment have different performance curve, the human-machine interface 200 allows displaying, for each equipment positioned in the sub-interface 204, possible performance curves and selecting one of the possible performance curves for said equipment.

[0098] The received operating information is derived from said human machine interface 200. The model of the at least one surface configuration is derived from the received operating information.

[0099] More particularly, here, a Python script is generated corresponding to the model, for each surface configuration, here from the surface configuration representation and associated information received through the human-machine interface 200.

[0100] For each surface configuration, at least one production and / or injection profile and the associated Green House Gas emissions associated with said surface configuration in the corresponding model, for the or each production and / or injection profile, is calculated.

[0101] The production profile is, for example, the quantity of hydrocarbon extracted from the well(s). The considered hydrocarbon is, for example, oil. Alternatively or additionally, the considered hydrocarbon is, for example, gas.

[0102] The injection profile is, for example, the quantity of captured carbon injected into the well(s).

[0103] More particularly, the method comprises providing at least one site forecasting model of site performance of the site.

[0104] The at least one production or / injection profile and the associated Green House Gas emissions profiles are generated from at least one site forecasting model of site performance of the site.

[0105] The model of the at least one surface configuration is integrated into the at least one site forecasting model.

[0106] More particularly, the human-machine interface enables generating a mean to integrate the surface configuration representation and associated information, including for example associated GHG emissions according to the associated performance curves, into the at least one site forecasting model.

[0107] Here, the Python script corresponding to the model, for each surface configuration, is inserted into a production forecasting software.

[0108] The production forecasting software is, for example, the software GAP developed by Petroleum Experts or INTERSECT developed by Schlumberger.

[0109] The method comprises calculating an injection and / or production profile of the surface configuration based on the site forecasting model, and deriving the associated GHG emissions for said profile based on the surface configuration model.

[0110] The calculated emissions corresponding to an injection and / or production profile are based at least on the number, the nature and the arrangement of the surface equipment received and on which basis the surface configuration model was generated. The calculated emissions corresponding to an injection and / or production profile are here calculated from the performance curve(s) of the surface equipment of the surface configuration.

[0111] The Green House Gas emissions considered during the calculating comprises the emissions emitted by burning hydrocarbon on site to provide energy for the surface facility and the emissions associated to energy imported to the surface facility, and advantageously the emissions from flaring and venting.

[0112] During calculating the GHG emissions associated with a given surface configuration for a given production and / or injection profile, the calculated emissions are the minimum emissions for said given surface configuration and said given production and / or injection profile, in particular regarding different possible operations of the surface configuration.

[0113] More particularly, with a given surface configuration, for a forecasted injection and / or production value, said value may be obtained by operating the surface equipment according to different possible operations. The calculated GHG emissions associated with said given surface configuration for said value are the emissions of operating the surface equipment according to the operation that produces the least GHG emissions.

[0114] The calculating step, for example, includes calculating the associated GHG emissions for each possible operation of the surface configuration for said given production and / or injection profile, and selecting the minimum.

[0115] Alternatively, all the associated GHG emissions for all the possible operations are not calculated, some possible operations being dismissed beforehand as particularly GHG emitting.

[0116] For an easy example, in the example of figure 1 , there are, for example, a plurality of compressors in series on the gas line, that may have different performance curves. Thus, to compress the gas, one may use only a first compressor, only a second compressor, etc. or a mix of all the above according to different ratios. In the present scenario, each compressor uses electricity that is obtained by burning gas - said emissions are considered below. Alternatively, compressors use electricity generated by the turbines. Using only the first compressor to obtain a desired gas flow, for example, produces x1 emissions, using only the second compressor x2 emissions, using the first compressor and the second compressor at equal parts x12, etc. The minimum between x1 , x2, x12... corresponds to the associated GHG emissions for the subservice of obtaining said desired gas flow.

[0117] Thus, the calculated associated GHG emissions correspond to the emissions with an optimized operation of the surface equipment of the surface facility. In one embodiment, the at least one surface configuration comprises at least one equipment for producing renewable energy used by the site. The model comprises estimated energy production and storage by said equipment.

[0118] Thus, the calculating takes into account the energy produced and stored by said renewable energy producing equipment, and the calculated Green House Gas emissions are accordingly reduced compared to using a non-renewable source of energy, for example that would have been retrieved from the outside electrical network.

[0119] The calculated predictions of the production and / or injection profile and the associated Green House Gas emissions are made with a given pitch for a given period, e.g. with a pitch of one day, for example for twenty years.

[0120] In one embodiment, the method further comprises displaying 106, for the or each surface configuration, the or each production and / or injection profile and the respective emissions associated to said or each production and / or injection profile.

[0121] More particularly, a human-machine interface comprises a display 300, the or each production and / or injection profile 302 and the respective GHG emissions 304 associated to said or each production and / or injection profile being displayed on said display, for example as depicted on figure 4.

[0122] The or each production and / or injection profile indicates the calculated production P and / or injection values as a function of time t.

[0123] The associated GHG emissions E are similarly displayed as a function of time t.

[0124] Additionally or alternatively, the total cumulative associated GHG emissions for a given period of production and / or injection are displayed.

[0125] Additionally or alternatively, the method further comprises building 108 the surface facility or modifying 110 an existing surface facility of the hydrocarbon extraction or injection site, such that said surface facility is as in one of the at least one surface configuration, such as to limit the associated Green House Gas emissions in regard to production and / or injection.

[0126] In one embodiment, the surface facility of the site was not already built, such that the surface facility of the site is build following the calculating step.

[0127] The surface configuration(s) of the previously described step of the method correspond(s) to possible arrangements of surface equipment for the surface facility of the site.

[0128] Thus, the method allows testing different surface configurations and choosing the preferred tested surface configuration in regard to production and / or injection and the associated GHG emissions, in order to build said surface facility according to said preferred configuration. In another embodiment, the site with an existing surface facility is already previously built.

[0129] The surface configuration(s) of the previously described step of the method correspond(s) to possible modification(s) to the existing surface facility of the site.

[0130] Thus, the method allows testing different surface modifications and choosing the preferred tested surface configuration in regard to production and / or injection and the associated GHG emissions, in order to adapt the existing surface facility according to said preferred configuration.

[0131] In one embodiment, the method comprises further modifying at least one of the surface configuration(s), and calculating the Green House Gas emissions associated with the modified surface configuration, for the or each production profile.

[0132] Thus, the method allows trying to optimize the surface configuration in regard to GHG emissions for a given production and / or injection profile.

[0133] Alternatively or additionally, the method further comprises adapting the operation of the hydrocarbon extraction or injection site according to one of the at least one generated production and / or injection profile, in order to reduce the associated Green House Gas emissions.

[0134] The method allows calculating the GHG emissions associated to different production and / or injection profile, such as to compare the respective associated GHG emissions.

[0135] In one embodiment, the method comprises further modifying the production and / or injection profile, and calculating the Green House Gas emissions associated with each or the surface configuration for the or each modified production and / or injection profile.

[0136] Thus, the method allows trying to optimize the production and / or injection profile in regard to GHG emissions for a given surface configuration.

[0137] In one embodiment, the method further comprises the following steps:

[0138] - providing a maximum threshold for the Green House Gas emissions during a time unit, for example linked to a strategic ecologic target or a local requirement, and

[0139] - calculating, for each or the surface configuration, a complying production profile, such that the emissions associated to said complying production profile are below the maximum threshold at all time.

[0140] A feedback loop from the emissions calculation to the site forecasting model of site performance of the site is, for example, set up.

[0141] Said feedback loop is, for example, also integrated into the at least one site forecasting model.

[0142] Thus, the method comprises calculating the GHG emissions corresponding to a injection and / or production profile for a given surface configuration. If the calculated GHG emissions are above the maximum threshold, the method further comprises adapting the injection and / or production profile, in particular lowering the corresponding injection and / or production, here using the feedback loop, and calculating the GHG emissions corresponding to said modified injection and / or production profile, said step being reiterated, as long as the calculated GHG emissions are above the maximum threshold.

[0143] This allows determining an injection and / or production profile, for which the associated GHG emissions are below the desired threshold.

[0144] The method of the invention is thus particularly advantageous in that it allows identifying the emissions linked to one or different production profiles for a given configuration. This then allows, for example, taking corresponding actions, such as modifying or building a site based on said results or modify the production and / or injection profile in operation, to reduce GHG emissions.

[0145] The invention further relates to an electronic device for configuring a hydrocarbon extraction or injection site comprising at least one well and a surface facility with lowest Green House Gas (GHG) emissions.
