BACKGROUND

Field of the invention

[0002] The present invention generally relates to well completion systems, and more specifically to intelligent systems for completion through production pipes. However, the indication of an example of application is only to simplify the detailed description, and should not be understood as a limitation. Various embodiments of the ideas shown here can be used in a wide variety of applications and technical areas.

Description of Related Art

[0003] The following descriptions and examples are not recognized as prior art even though they are incorporated in this chapter.

[0004] When an existing oil well begins to empty or the produced water proportion becomes too high, there is a need to shut off or choke off the previously producing formation and drill a secondary branch. The secondary branch may be drilled in the same well to a new oil and/or gas pocket. In general, the secondary branch can be referred to as a side step or a multilateral branch. The process of drilling a lateral is necessary to renew a producing oil well without the large costs and expenses associated with drilling an entirely new well.

[0005] These new laterals are often drilled while the existing completion string remains in the wellbore. This type of drilling is often called TTD drilling (Through Tubing Drilling) or coiled pipe drilling. TTD drilling creates new tapping points in side branches or a sequence of side branches, often called multilateral steps. With this type of well construction, there are challenges associated with the completion of these new tapping points as a result of the limitations of the existing upper completion sections. The existing upper completion sections generally reduce the hole diameter in the well system available for running in a production piped (through tubing) completion. A further challenge is communication with the production pipeline completion to effect selective control and data measurement. There are of course also other challenges beyond the given examples, which can be solved by this description.

SUMMARY

[0006]Embodiments of the system or method for which protection is required may comprise a production piped completion system driven into a side hole. The production piped completion may comprise production pipe connected to a flow control valve and one or more sensors that measure at least one feature at the side hole. In addition, the production piped completion may comprise one of a male or female wet connect system (wet connect system) arranged to be communicatively connected to the flow control valve and the one or more sensors. A corresponding male or female wet coupling system may be placed in communication with said one of a male or female wet coupling system to control the flow control valve and/or to communicate the at least one draft at the side hole.

[0007] In other embodiments, the coupling system may comprise a wireless communication module configured to communicate wirelessly with a location on the surface while connected to an upper portion of the production pipelined completion. In some embodiments, the production pipelined completion may include a wireless communication link arranged to communicate wirelessly with a location on the surface above a gap. In this last example, the wireless communication link may comprise a coil device for inductive communication across the gap. Embodiments of the invention for which protection is required may also include a method for installing a production pipeline completion system with the coupling system.

DETAILED DESCRIPTION

[0021] In the following description, a number of details are explained to provide an understanding of some illustrative embodiments of the present invention. However, it will be understood by those skilled in the art that various embodiments of the present invention may be practiced without these details, and that a number of variations or modifications from the described embodiments may be possible.

[0022] In the description and in the appended claims, the terms "connect", "connection", "connected", "in connection with" and "connecting" and the like are used in the sense of "in direct connection with" or "in connection with via one or more items"; and the term "set" is used in the sense of "one element" or "more than one element". Furthermore, the terms "connect", "connection", "connected", "connected together" and "connected to" are used in the sense of "directly connected" or "connected via one or more elements". The words "up" and "down", "upper" and "lower", "upward" and downward", "upstream" and "downstream"; "above" and "below"; and other similar words denoting relative positions above or below a given point or element, is used in this description to more clearly describe some embodiments of the invention.

[0023] Embodiments of this invention generally relate to a side track or a side branch that is drilled from an existing completion, referred to as TTD drilling. In addition, embodiments also relate to how a siding or a siding can be completed without extracting the existing completion and without or with minimal modifications to the existing surface infrastructure, referred to as production piped completion. In some embodiments, the production piped completion systems relate to intelligent completions or completion systems that can be adapted based on conditions occurring in the well.

[0024] Figures 1 and 2 show an embodiment of a production pipeline completion system 20 with a communication connection or a coupling system 21 comprising a male wet coupling part 22 which is run on a cable 24, according to aspects of the present invention. As shown, a well system 26 may comprise an existing upper completion 28 with completion components such as production pipe 30, e.g. a 7-inch production pipe, and a Surface Controlled Subsurface Safety Valve (SCSSV) 32, e.g. a 17.8 cm (7-inch) valve. The production pipe 30 and SCSSV 32 can be driven into a wellbore 34, e.g. a lined wellbore comprising a production casing 36, such as a 9-5/8-inch production casing. In the example shown, the annular space between the production pipe 30 and the production casing pipe 36 can be sealed off with a production gasket 38, e.g. a 9-5/8-inch production gasket.

[0025] When the well is emptied or begins to produce an excessive amount of water, a production diverter, or a "whipstock" 40, may be driven down inside the production pipe 30. The guide wedge 40 facilitates a coiled pipe-based or TTD drilling operation to drill a siding or a side bore 42 to a new production site. After the side bore 42 is drilled, the open side hole is completed to regulate the flow of production fluid from the borehole. In some embodiments, the sidehole 42 may include more than one producing zone 44, such as in a multilateral well. As an example, three controllable zones 44 are separated by open hole gaskets 46, e.g. swelling seals, shown here. In some cases, at least one passive inflow control device, or "ICD - Inflow Control Device" monitoring instrument, may be driven into the side branch.

[0026] In order to complete the sidebore 42, the components of a throughhole completion must be able to pass through the smallest diameter of the existing upper completion 28.1 in this case the SCSSV 32 limits the outside diameter of the production piped completion to a limited diameter, e.g. . a diameter of 14.605 cm (5-3/4 inch). As shown, a production piped completion 48 is consequently formed by a production pipe 50 with a smaller diameter, for example a production pipe with a diameter of 10.16 cm

(4 inches). The thinner production pipe 50 is sealed to the inside diameter of the larger production pipe 30 via a port seal 52, e.g. a 17.8 cm (7 inch) port gasket. The gasket 52 seals off the annulus between the thinner production pipe 50 and the larger, surrounding production pipe 30. An opening 54 is formed above the port gasket 52 so that fluid can flow from the side hole to the surface through the larger production pipe 30 (the opening is more clearly seen in figure 2) .

[0027] A number of electrically actuated flow control valves (FCV) 56 are incorporated into the illustrated embodiment of a production pipeline completion 48. The valves 56 may be connected to sensors 58 to measure and transmit one or more sidehole parameters, such as flow rate, pressure, temperature, water content, resistivity, etc. The information can be connected to a female wet coupling 60 arranged at the top of the production piped completion 48. The female wet coupling 60 and the male wet coupling 22 form a connection or coupling system 21, which in this case is a wet coupling system. In addition, a cable 62 may also enable communication and/or supply power for individual control of each of the electric FCV valves 56 downhole. A rechargeable or towable battery/power source 64 is connected to the female wet connector 60 and the cable 62. In this example, the power source 64 can be arranged to only supply power to the various sensors 58 downhole. Due to the relatively low power consumption of the sensors 58, this can help to minimize the size of the power supply 64. In other embodiments, the power source 64 can of course be used for electrical operation of the FCV valves 56.

[0028] To download data, charge the battery 64 and activate the FCV valves 56, the male wet connector 22 can be driven into the hole of the cable 24.1 in some cases the male wet connector 22 can be pulled out of the hole during production. In other cases, the cable 24 connecting the male wet connector 22 to the surface may be used to enable monitoring and control of the side bore 42 in real time during production periods. In addition, the male and female wet connectors 22, 60 may be electrically connected to each other through inductive or electromagnetic coupling or through electrical contact between the male and female wet connector components.

[0029] As shown in more detail in Figure 2, the male and female wet coupling components 22, 60 can be connected together through a holding mechanism 66. In this embodiment, the wet coupling components 22, 60 are shown interconnected through an inductive coupling 68, although the components are not limited to the in this example. In other cases, the wet coupling components 22, 60 may comprise a direct electrical connection. The inductive coupler-based wet switching system shown can enable one- or two-way communication of power, signals, data transfer, or a combination thereof. In this concrete example, an electronics unit (cartridge) 70 is connected to the cable 62 below the inductive coupling 68; and electronics 72 are arranged inside the male wet connector 22.

[0030] Figure 3 illustrates another embodiment of the wet connector components 22, 60. In this case, the male wet connector 22 comprises a drawable power source 74 transported downhole and connected to the upper end of the production piped completion 48. The drawable power source 74 can be retrieved regularly and does that the production piped completion 48 can be made with less or without permanently mounted power supplies. In addition to supplying power, the towable power supply 74 may also have a storage component 76 for recording data obtained by the sensors 58. Once retrieved to the surface, the data may be downloaded and processed for future control of the well system.

[0031] The drawable power source 74 can also be used during production. Fluid can flow from the smaller, production piped completion, e.g. the completion 48, to the larger, existing production pipe, e.g. the upper complement 28, as indicated by the arrows 78 in the figure. Power supply and control of the electronic FCV valves 56 (not shown in this figure) can take place autonomously downhole or by means of wireless signals.

[0032] Figure 4 illustrates another embodiment of the production pipeline completion system 20.1 this embodiment, the production pipeline completion system 20 includes a production pipeline completion 48 corresponding to the production pipeline completion described in connection with Figure 1. To make the description shorter, only the differences will therefore be explained in detail. Instead of the wet coupling system that primarily communicates electrical power and/or signals, this embodiment has a coupling system 21 that includes a hydraulic and electrical wet coupling system 80. The electrical components 82 of the wet coupling system 80 can communicate electrical power and/or signals through inductive coupling or direct electrical contact. In addition to the electrical components 82, there are also hydraulic components 84 in the wet coupling system 80. The hydraulic components 84 are connected to the top of the production piped completion 48, and supply hydraulic power to the FCV valves 56. In this case, hydraulic FCV valves are arranged in the the different production zones 44 in the side hole 42. The hydraulic-electric wet coupling system 80 may be hydraulically and electrically connected to the surface of the well system through a hybrid cable 86 comprising respective hydraulic and electrical conduits 88, 90.

[0033] The hydraulic component 84 of the wet clutch system 80 can be used to provide adjustment of the hydraulic FCV valves 56. Use of hydraulic FCV valves removes the need for relatively large permanent, towable or rechargeable power supplies. In addition, the open hole packings 46 (if they are not electrically set or swelling packings) can be hydraulically set after driving the production piped completion into the side bore. In some cases, a male hydraulic wet coupling 92 may be disconnected from a female hydraulic wet coupling 94 and pulled out of the hole during production from the side bore 42.

[0034] Figure 5 illustrates another embodiment of the production pipeline completion system 20.1 this embodiment, the system 20 comprises a retractable communication module 96. The retractable communication module 96 can comprise a wireless telemetry module 98, a male part of an inductive coupler 100 for the inductive coupling 68, a downhole power storage/generator module 102 and/or other suitable components. The towable communication module 96 can be guided downhole and connected to the top of the production piped completion 48.

[0035] Power and data can be communicated between the retractable communication module 96 and the production pipeline completion 48 via the inductive coupler male part 100 and an associated inductive coupler female part 104 in the wet coupling connection system 21. Although male and female parts of inductive couplers 100, 104 is shown to create a power and/or communication path between the towable communication module 96 and the remainder of the production pipelined completion 48, other embodiments may include other forms of wet coupling (ie, making power/control connections downhole) to interconnect the towable communication module 96 and the production piped completion 48. For example, in some cases the wet coupling may comprise electrical terminals in direct contact with each other. In addition, the inductive coupler male part 100 of the retractable communication module 96 and the inductive coupler female part 104 can be connected together by means of a holding mechanism, such as the holding mechanism 66.

[0036] As described above, the retractable communication module 96 can comprise a downhole power generation module and/or power storage module 102. The power generated by the module 102 in the retractable communication module 96 can be used to supply the sensors 58, the electric flow control valves 56 and the wireless communication module 98 The capacity and performance of the power module 102 can be determined based on the number of electrical components to be activated and on the desired rate of replacement. The power stores in the module 102 can comprise batteries, capacitors or other forms of power stores. In some embodiments, the module 102 comprises

power generation function.

[0037] As can be seen in Figure 5, this embodiment of the retractable communication module 96 includes a bore 106 to enable the flow of production fluid when the retractable communication module 96 is inserted. Accordingly, the module 102 may include a power generator device 108, such as a turbine, to generate power from the fluid flowing through the towable communication module 96. At various predetermined time intervals, or when a sensor indicates so, the towable communication module 96 may be retrieved and replaced out to ensure future operation of the production pipeline completion.

[0038] Data obtained by the sensors, e.g. the sensors 58, can be transmitted through the cable 62 to the inductive coupler system 68 (ie the male part and the female part 100, 104 of the inductive coupler). From the inductive coupler system 68, the data can be sent to the wireless telemetry module 98. The wireless telemetry module 98 can be arranged to send data and control signals between the surface and the production piped completion 48 by means of an associated wireless telemetry module 110 arranged on the surface of the well system 26 This ensures a wireless communication link between the production piped completion 48 and an operator located on the surface of the well.

[0039] Figure 6 illustrates another embodiment of a production pipelined completion system 20. The production pipelined completion system illustrated in Figure 6 may be equivalent to the production pipelined completion system described in connection with Figure 5. To shorten the description, only the differences will therefore be explained in detail.

[0040] In the embodiment illustrated in Figure 6, the production piped completion 48 may be at a depth where wireless telemetry is either impractical or ineffective. To compensate for the depth, a sequence of wireless short-hop telemetry modules 112 may be used. The wireless short-hop telemetry modules 112 may comprise one or more anchors 114 to secure or attach the modules 112 to the existing upper completion 28/production pipe 30.1 in addition, the wireless short-hop telemetry modules 112 may further comprise a length of production pipe 114, upper and lower wireless telemetry modules 112 and a cable 116 connecting the upper and lower wireless telemetry modules. Although not shown in this figure, the short-hop telemetry modules 112 may also include the power storage/generation module 102 to supply power to the various electrical components associated with the wireless short-hop telemetry modules 112 .

[0041] The wireless short-hop telemetry modules 112 may be tractable, corresponding to the tractable communication module 96 connected to the production pipeline completion 48. The short-hop modules 112 may communicate data, power and other signals between the electric flow control valves 56, the sensors 58 and/or the lower the wireless telemetry modules in an adjacent wireless short-hop telemetry module 112. These signals can be sent to the upper wireless telemetry module 112 over the cable 116. The upper wireless telemetry module 112 can then communicate data, power and other signals to a wireless telemetry module 112 arranged on the surface. Because the communication between the cooperating wireless telemetry modules 112 now goes over relatively shorter distances, the modules 112 can be made smaller or have lower power than a system that transmits wirelessly to the surface from the production pipelined completion 48.

[0042] As shown, in some embodiments, a space between cooperating wireless telemetry modules may be necessary at a given location in order for the upper complement 28 to be able to retain a previous function. In the embodiment illustrated in Figure 6, there is, for example, a wireless short-hop transmission over SCSSV

32, so that SCSSV 32 can be closed when necessary. Furthermore, only one wireless short-hop telemetry module is shown above the production pipeline completion 48. However, two or more wireless short-hop telemetry modules 112 may be used as necessary. In some cases, one can use as many standardized wireless short-hop telemetry modules as are necessary to ensure a satisfactory coverage of the distance between the production piped completion 48 and the wireless telemetry module 112 arranged on the surface of the well system 26.

[0043] Figure 7 illustrates another explanatory embodiment of the production pipelined completion system 20. The production pipelined completion system shown can be equivalent to the production pipelined completion system described in connection with Figure 5. To shorten the description, only the differences will therefore be explained in detail.

[0044] The retractable wireless communication modules in Figures 5 and 6 are modified in the embodiment shown in Figure 7.1 this last embodiment, the wireless telemetry module is replaced by a data printer 118, several registration capsules 120 and a wireless signal receiver 122, where the wireless signal receiver 122 is suitable to receive a wireless signal selected from a pressure pulse inside the pipe sent from the surface, a low frequency seismic/acoustic signal, an EM signal or a radio frequency signal. As in the previous towable wireless communication modules, a downhole power storage/generator module, e.g. module 102, and a wet coupling, such as one of the wet coupling systems 21 described above, be incorporated to power and couple the towable wireless communication module to the top of the production piped completion 48.

[0045] Data from the side bore 42 and other systems can be communicated from the sensors

58 provided in the production piped completion 48 and stored on a recording capsule 120. A wireless, low-frequency seismic/acoustic signal can be sent from the surface to the wireless, low-frequency seismic/acoustic signal receiver 122. Alternatively, a pressure pulse in the fluid inside the pipe can be sent from the surface of the pressure sensor 122. The information transmitted from the surface by the low-frequency seismic/acoustic signal is used to set and control the electronic flow control valves 56 in the production pipeline completion 48. In addition, the wireless, low-frequency seismic/acoustic signal receiver 122 can instruct a capsule container 124 to release the recording capsule 120 to which the data is written. The recording capsule 120 can flow to the surface and provide a reader on the surface with information about the environment and systems downhole. In other embodiments, the recording capsules 120 may be released at a predetermined time interval or upon another event downhole, such as detection of water breakthrough at one of the sensors.

The registration capsule system represents a cheaper alternative to the costs and expenses associated with real-time systems.

[0046] The retractable wireless communication module can be replaced at predetermined time intervals or upon the occurrence of an event, such as parameters indicating that the life of the power storage module 102 is nearing its end or that the supply of registration capsules 120 from the capsule container 124 has been used up. When replaced, new registration capsules 120 can be provided for a further period of time with monitoring of the downhole environment.

[0047] Figure 8 illustrates another embodiment of the production pipelined completion system 20.1 this embodiment, the system 20 includes a wireless communication connection 126. The wireless communication connection 126 can be used in a well system 26 with features, designs and components that are the same as or corresponding to many of the components described above in connection with the embodiments illustrated in figures 1-7. As described above, the well system 26 can for example include the existing upper completion 28 with completion components such as production pipe 30 and a surface controlled underground safety valve (SCSSV) 32. The production pipe 30 and SCSSV 32 can be driven into a lined wellbore 34 with production casing 36.1 the example shown the annulus between the production pipe 30 and the production casing pipe 36 above can be sealed with a production seal 38.

[0048] When the well is drained or begins to produce an excessive proportion of water, the production diverter 40 can be driven in through the production pipe 30. The production diverter 40 facilitates a coiled tubing-based or TTD drilling operation to drill the sidetrack or sidebore 42 to a new production location. After the side bore 42 is drilled, the open side hole is completed to control the flow of production fluid from the borehole. In some embodiments, the side hole 42 may comprise more than one production zone 44, such as in a multi-zone well.

[0049] To complete the side bore 42, as above, the components of the wellbore completion 48 must be able to pass through the smallest diameter of the existing upper completion 28. For example, the SCSSV 32 may limit the outside diameter of the production piped completion 48. The production pipe 50 in the production piped completion 48 is sealed to the inside diameter of the existing production pipe 30 by means of a port gasket 52. The port gasket 52 seals off the annulus between the production pipe 50 and the larger production pipe 30.

[0050] Incorporated in this embodiment, the production piped completion 48 includes a corresponding number of the electrically actuated flow control valves (FCV) 56. The valves may be connected to sensors 58 arranged to measure and output one or more sidehole parameters, such as flow rate, pressure, temperature, water content, resistivity etc. The information can be sent from (or to) the production piped completion over the wireless communication connection 126 connected to the cable 62.1 addition, the cable 62 can also enable communication and/or supply power for individual control of each of the electric FCV- the valves 56 downhole.

[0051] At an upper section of the thinner production pipe 50 in the production piped completion 48 illustrated in this embodiment, the wireless communication link 126 is provided to cover a gap 128, such as a gap over the SCSSV 32.1 this particular example makes the gap 128 over the SCSSV 32 that the safety valve in the existing upper completion 28 can still function as it should in the event of some form of failure in the well system. In the illustrated example, the gap 128 is chosen to be on the order of 20 to 30 cm (8 to 12 inches) wide, which is sufficient to ensure that the SCSSV flap functions. When the SCSSV 32 is closed, in some embodiments, communication may be limited across this gap.

[0052] As illustrated, the wireless communication link 126 has a coil device 130 with a coil 132 disposed at an upper section of the production pipe 50 in the production piped completion 48. A cooperating coil 134 in the coil device 130 is disposed on the other side of the space 128. The coil device 130 can stand across the axis of the production pipe 50 or at an angle in relation to the production pipe 50, as illustrated in the alternative coil device in Figure 9.1 this embodiment, the opening 54 is located directly below the coil device 130 and enables the flow of production fluid around the coil device 130 (inside the annulus between the smaller diameter production pipe 50 and the larger production pipe 30).

[0053] The cooperating coil 134 in the coil assembly 130 may be disposed at the lower end of a production pipe section 136 that goes up to the surface. As an example, the production pipe 136 can have the same diameter as the production pipe 50. An opening 138 can be made through the side wall of the production pipe 136, corresponding to the opening 54, directly above the cooperating coil 134 so that production fluid can flow around the associated coil device 130 (from the annulus inside the the larger production tube 30 and back into the interior of the thinner production tube section 136).

[0054] The coil 132 and the cooperating coil 134 may be connected by respective cables, such as the cables 62 and 24. It should be noted that both the coil 132 and the cooperating coil 134 may be provided in a variety of different coil arrangements and designs that employ single coils or several coils. The coil 132 may be connected via the cable 62 to the electrical components of the production piped completion 48 entering the side bore 42, such as the electric flow control valves 56 and associated sensors 58. The cooperating coil 134 may be connected via the cable 24 to a location on the surface for monitoring and/or controlling an operator.

[0055] Figure 10 illustrates another embodiment of a production pipelined completion system 20. The production pipelined completion system 20 shown can be similar to the production pipelined completion system 20 described in connection with Figure 8. To shorten the description, only the differences will therefore be explained in detail.

[0056] In the embodiment in Figure 10, the coil device 130 in the previous embodiment can be replaced with a toroid coil device 140. The toroid coil device 140 can be arranged to function in a similar way to the coil device 130 described above. As shown in the figure, the toroid coil device 140 can be arranged so that the valve flap in an SCSSV 32 can still function as it should. A gap 128, for example from 20 to 30 cm, is formed between cooperating toroidal coils 142, 144 in the toroidal coil assembly 140. In this example, the gap size is chosen to allow the valve flap to be operated while still allowing a reasonable level of transmission efficiency and effectiveness of power and/or communication signals between the toroid coil devices. A cross section of one of the toroidal coils 142 or 144 is illustrated in figure 11.1 this example the toroidal coils 142, 144 are arranged respectively at the upper end of the production pipe 50 and at the lower end of the production pipe section 136. The coil device 130 or the toroidal coil device 140 can be used to relay communication signals and/or power signals above 128.

[0057] Elements of the embodiments have been introduced using singular forms. The singular form is meant to mean that it is one or more of the elements. Words such as "comprising", "with" and "having" are intended to be inclusive so that there may be additional elements beyond the specified elements. The word "or", when used with a list of at least two items, is intended to mean any item or any combination of items.

[0058] Although only a few embodiments of the present invention have been described in detail above, those skilled in the art will readily see that many modifications are possible without departing from the ideas of this invention. Accordingly, such modifications are intended to be encompassed within the scope of this invention, as defined in the claims.
