CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application is a U.S. Non-Provisional Patent Application claiming benefit of U.S. Provisional Patent Application No. 63/635,272, entitled “ELECTRIC FORMATION ISOLATION VALVE”, filed April 17, 2024, which is herein incorporated by reference.
BACKGROUND

[0003] Production of subterranean fluid typically includes drilling of a wellbore into a reservoir rich in subterranean fluid, completion of the wellbore, and production or retrieval of the subterranean fluid from a downhole location. In some instances, the reservoir may include more than one downhole layers, locations, or zones containing subterranean fluid. To improve efficiency, it may be desirable to produce from the more than one downhole location at the same time, using a single production or tube string. To do so, the wellbore may be completed in the multiple zones, such as by casing and perforating the wellbore to provide stability and enable fluid flow. During completion, the multiple zones may be fluidly isolated via one or more downhole isolation devices to reduce deleterious effects, such as due to pressure differences between layers. Additionally, during production, it may also be desirable to fluidly isolate the multiple zones within the wellbore, for example, to perform maintenance tests. Conventional systems may include mechanical or pressure actuated isolation devices to isolate one or more portions of the wellbore and/or tube string. However, improved isolation devices may be desirable for increased control of downhole fluid flow and increased frequency of isolation.

[0022] As such, embodiments of the present application are directed towards an electronic passage isolation device (e.g., electronic formation isolation valve (eFIV)) that is configured to seal or isolate two portions of a passage of a tube string (e.g., tool string, production string). For example, the electronic passage isolation device may include a ball valve positioned within the passage and configured to rotate to expose an orifice of the ball valve to the passage in an open configuration and may rotate to block the orifice in the closed configuration. In the open configuration, fluid (e.g., subterranean fluid, hydrocarbon fluid) may be directed through the ball valve, fluidly coupling a portion of the passage up hole of the ball valve and a portion of the passage downhole of the ball valve. In the closed configuration, flow of fluid through the ball valve may be disabled, fluidly isolating the two portions of the passage. The ball valve may be coupled (e.g., mechanically coupled) to an actuator (e.g., electronic actuator), wherein the actuator may selectively actuate the ball valve to obtain desired flow (or suspension) of fluid within the passage. For example, the electronic actuator may include an electric drive configured to linearly (e.g., axially) translate one or more components of the passage isolation device. A yoke (e.g., yoke mechanism) coupled to the ball valve may translate the linear motion of the components into a rotational movement of the ball valve, opening or closing the ball valve and isolating portions of the passage. By electronically actuating the passage isolation device, an operator may perform an increased number of maintenance checks directed towards the isolated portions of the passage, compared to traditional systems (e.g., mechanical isolation devices).
[0023] With the preceding in mind, FIG. 1 is a schematic view of an embodiment of an offshore system 10 for production of subterranean fluids (e.g., oil, gas, fluid, hydrocarbon fluid). The offshore system 10 may include various components configured to enable production of fluid from a geological formation 12 (e.g., formation, surrounding formation), which may correspond to a volume of subsurface rock (e.g., subterranean formation) that contains various layers (e.g., rock layers, porous layers, aquifers,
impermeable layers). Tn many instances, the geological formation 12 may include more than one producing layers (e.g., hydrocarbon bearing formation, reservoir, producing zone) at varying depths. For example, the geological formation 12 may include a first producing layer 16 (e.g., first zone) at a first depth (e.g., closer to a surface 20, up hole) and a second producing layer 24, below the first producing layer 16 at a second depth (e.g., downhole). The offshore system 10 may include a wellbore 28 (e.g., producing wellbore, completed wellbore) drilled from the surface 20 into and through the geological formation 12 to form an open hole 32 within the geological formation 12, where the wellbore 28 intersects the various layers in the subsurface rock of the geological formation 12 (e.g., the first and second producing layers 16, 24). In the illustrated embodiment, the offshore system 10 may include an offshore vessel or platform 36 in which a tube string 40 may extend from a sea level 44 to the surface 20 where a wellhead 48 (e.g., Christmas tree) is situated. Before production, the wellbore 28 may typically be completed to stabilize the open hole 32 (e.g., preventing cave ins) and to facilitate fluid flow into and out of the wellbore 28.
[0024] For example, a casing 52 (e.g., cement casing, tube) of the wellbore 28 may be inserted into the open hole 32 to provide a path for the tube string 40 into the geological formation 12 and to provide stability, reducing or preventing collapse of the wellbore 28. In some instances, only a first portion (e.g., upper portion) of the wellbore 28 may be cased with the casing 52, and a second portion (e.g., bottom portion) of the wellbore 28 may be exposed to the open hole 32 (e.g., illustrated in FIGS. 8 and 9). In some embodiments, an annulus or space between the casing 52 and the open hole 32 may be cemented to further provide stability to the wellbore 28.
[0025] In certain embodiments, the casing 52, cement within the annulus, and/or the geological formation 12 may be perforated in one or more interval that intersects and/or aligns with a producing layer (e.g., the first producing layer 16, the second producing layer 24), thereby facilitating subterranean fluid flow into the wellbore 28 from the geological formation 12. For example, in certain embodiments, a perforating gun (not shown) may be deployed into the wellbore 28 (e.g., the casing 52, the open hole 32) and positioned at the intersection of a producing layer with the wellbore 28. Upon locating the perforating
gun within the interval, the perforating gun may be operated to perforate through the casing 52 into a producing layer.
[0026] In multi zone or multi producing layer geological formations, such as the geological formation 12, the wellbore 28 may be completed at separate times. For example, a first portion (e.g., bottom portion) of the wellbore 28 at a first location (e.g., the second producing layer 24, lower layer) may be cased at a first time. Subsequently, the perforating gun may be lowered to the first location to perforate the casing 52, cement, and the second producing layer 24. After, a first portion of the tube string 40 may be inserted into the wellbore 28 to the first location and may be operable to fluidly isolate the first portion of the wellbore 28 from a second portion (e.g., up hole) of the wellbore 28. The second portion of the wellbore 28 may be subsequently completed at a second time while the first portion is isolated, followed by the insertion of a second portion of the tube string 40. Upon insertion, the second portion of the tube string 40 may couple (e.g., mechanically, electronically, fluidly) with the first portion of the tube string 40 to define the full tube string 40. Perforating multiple producing layers of a single wellbore 28 may increase production and reduce additional wellbores that may be used to produce from additional layers, reducing costs. Unfortunately, each producing layer of a multiple producing layer geological formation 12 may include different characteristics, such as different fluid pressure, permeability, and/or fluid types. As such, to increase production efficiency, avoid unwanted fluids, and reduce formation damage, the tube string 40 may be configured to isolate (e.g., isolate within the wellbore 28, isolate within the tube string 40) the producing layers (e.g., fluid from the producing layers). For example, the wellbore 28 may be configured to isolate the first producing layer 16 (e.g., fluidly isolate) from the second producing layer 24 within the wellbore 28.
[0027] To this end, the wellbore 28 may include one or more wellbore isolation devices 64 configured to isolate (e.g., fluidly isolate) the multiple zones within the wellbore 28. For example, the wellbore isolation devices 64 may be configured to isolate fluid originating from the first producing layer 16 from fluid originating from the second producing layer 24 within the wellbore 28. That is, the wellbore isolation devices 64 may isolate a first annulus 68 between the tube string 40 and the casing 52 at a first location
(e g., downhole) from a second annulus 72 between the tube string 40 and the casing 52 at a second location (e.g., up hole). In an embodiment, the wellbore isolation device 64 may be a swellable device that may expand from the tube string 40 to abut or contact the casing 52, creating a seal (e.g., pressure tight seal) between the first annulus 68 and the second annulus 72. For example, in operation, a first portion of the tube string 40 including the wellbore isolation device 64 may be positioned in a lower portion of the wellbore 28. The wellbore isolation device 64 may expand or swell when in contact with a specific fluid to increase a size (e.g., diameter) to abut the casing 52 inner wall. In this way, the lower (e.g., downhole) portion of the wellbore 28 may be isolated from an upper portion (e.g., up hole), enabling completion of the upper portion without interference from fluid from the lower portion. In some embodiments, other types of wellbore isolation devices 64 may be utilized, such as mechanical packers.
[0028] As noted above, it may be desirable to additionally isolate the fluid of the first or second producing zones 16, 24 from within the tube string 40. For example, the wellbore 28 may include a passage 76 (e.g., flow path) extending through and along a length of the tube string 40 and configured to direct flow of fluids up hole (e.g., during production) or downhole (e.g., during flushing or depositing). As such, the tube string 40 may include one or more intake portions 80 configured to enable fluid flow into and/or out of the tube string 40. In some embodiments, the intake portions 80 may be positioned at varying depths to intake fluid from various locations, such as the various producing layers (e.g., the first producing layer 16, the second producing layer 24).
[0029] Selectively isolating a flow of fluid through the passage 76 of the wellbore 28 may provide a downhole barrier against pressure reversal, reduce formation damage, and minimize fluid loss. To this end, the tube string 40 may include one or more passage isolation devices 84 (e.g., electronic isolation valve, electronic ball valve, electronic gate valve, or electronic formation isolation valve (eFIV)) configured to isolate fluid flow from within the tube string 40 (e.g., the passage 76). For example, during engagement (e.g., closed), the passage isolation device 84 may fluidly isolate or seal a first portion 88 (e.g., downhole portion, bottom portion) of the passage 76 including a first flow 92 of fluid (e.g., flow originating from the second producing layer 24, flow received by intake portion 80A)
from a second portion 96 (e.g., up hole portion, upper portion) of the passage 76 including a second flow 100 of fluid (e.g., flow originating from the first producing layer 16, flow received by intake portion 80B). During disengagement (e.g., open), the passage isolation device 84 may fluidly couple the first portion 88 and the second portion 96 of the passage 76 to enable a combined flow 104 of the first flow 92 and the second flow 100. In an embodiment, the passage isolation device 84 may at least partially define the tube string 40. In the embodiments described herein, the passage isolation device 84 may be electronically actuated and controlled to ensure a desired flow of the first flow 92, the second flow 100, and/or the combined flow 104 to provide a downhole barrier against pressure reversal, reduce formation damage, and minimize fluid loss. Additionally or alternatively, an electronic passage isolation device (e.g., electronic isolation valve) may enable increased maintenance checks to ensure a proper seal of the passage 76, compared to traditional passage isolation valves.
[0030] To this end, the offshore system 10 may include a controller 108 (e.g., control system control panel, control circuitry, automation controller, programmable controller, surface controller) that is communicatively coupled to one or more components of the offshore system 10 (e.g., tube string 40, wellbore isolation device 64, passage isolation device 84, control system 120) and is configured to monitor, adjust, and/or otherwise control operation of the one or more components of the offshore system 10. For example, one or more control transfer devices, such as wires, cables, wireless communication devices, and the like, may communicatively couple the components of the offshore system 10 to the controller 108. That is, the components of the offshore system 10 may each have one or more communication components that facilitate wired or wireless (e.g., via a network) communication with the offshore system 10. In some embodiments, the communication components may include a network interface that enables the components of the offshore system 10 to communicate via various protocols such as EtherNet/IP, ControlNet, DeviceNet, or any other communication network protocol. Alternatively, the communication components may enable the components of the offshore system 10 to communicate via mobile telecommunications technology, Bluetooth®, near-field communications technology, and the like. As such, the components of the offshore system 10 may wirelessly communicate data between each other. In other embodiments,
operational control of certain components of the offshore system 10 may be regulated by one or more relays or switches (e.g., a 24 volt alternating current [VAC] relay).
[0031] The controller 53 may include processing circuitry 112 (e.g., processor), such as a microprocessor, which may execute software for controlling the components of the offshore system 10. The processing circuitry 112 may include multiple microprocessors, one or more “general-purpose” microprocessors, one or more special-purpose microprocessors, and/or one or more application specific integrated circuits (ASICS), or some combination thereof. For example, the processing circuitry 112 may include one or more reduced instruction set (RISC) processors.
[0032] The controller 108 may also include a memory device 116 (e.g., a memory) that may store information, such as instructions, executable code, control software, look up tables, configuration data, other data, or any combination thereof. The memory device 116 may include a volatile memory, such as random access memory (RAM), and/or a nonvolatile memory, such as read-only memory (ROM). The memory device 116 may store a variety of information and may be used for various purposes. For example, the memory device 116 may store processor-executable instructions including firmware or software for the processing circuitry 112 to execute, such as instructions for controlling components of the offshore system 10 (e g., passage isolation device 84). The memory device 116 may also store data relating to operating parameters of the offshore system 10 (e.g., measured parameters, set points, etc.). In some embodiments, the memory device 116 is a tangible, non-transitory, machine-readable-medium that may store machine- readable instructions for the processing circuitry 112 to execute. The memory device 116 may include ROM, flash memory, a hard drive, or any other suitable optical, magnetic, or solid-state storage medium, or a combination thereof.
[0033] Although FIG. 1 relates to the offshore system 10, it will be appreciated that embodiments of the present disclosure may be used in other types of wellbores at other locations, such as an onshore system (e.g., onshore well, land rig). Additionally, although a single passage isolation device 84 is illustrated in the embodiment of FIG. 1, it will be appreciated the wellbore 28 may include multiple (e g., more than one) passage isolation devices at different locations (e.g., depths) along the length of the passage 76 or tube string
40. For example, an additional passage isolation device 84 may be positioned above (e.g., up hole), below (e.g., downhole), and/or adjacent to the illustrated passage isolation device 84 to further isolate the wellbore 28, such as in instances of more producing layers (e.g., more than the illustrated first producing layer 16, second producing layer 24).
[0034] FIG. 2 is a schematic of an embodiment of a control system 120 associated with the offshore system 10 in accordance with one or more aspects of the present disclosure. The control system 120 may include the controller 108, an emergency shut off 124, and a real-time automatic control (RTAC) 128. Discussed above, the controller 108 may be communicatively coupled to one or more components or nodes of the control system 120 and configured to control the one or more components. For example, the controller 108 may be communicatively coupled to one or more downhole components of the tube string 40, such as the passage isolation device 84 (e.g., a controller of the passage isolation device 84), a flow control valve 132 configured to regulate fluid flow into the tube string 40, and/or one or more additional components 136. The emergency shut off 124 may be configured to detect or receive an undesirable condition of the offshore system 10 to adjust (e.g., suspend) operation of one or more components of the offshore system 10. In an embodiment, the emergency shut off 124 may be a manual trigger (e.g., button, switch) configured to be operated by a human operator. In some embodiments, the offshore system 10 may include the RTAC 128 configured to log data to monitor and control one or more downhole components (e.g., downhole tools, passage isolation device 84) allowing all downhole electric completion data to be acquired by a single surface acquisition system. In some embodiments, the controller 108, the emergency shut off 124, and the RTAC 128 may be “topside” or above sea level 44, such as onboard the platform 36.
[0035] In some embodiments, the one or more components of the tube string 40 (e.g., the passage isolation device 84) may be electrically coupled via a common cable or umbilical. For example, a cable 140 may electrically couple each of the passage isolation device 84, the flow control valve 132, the additional component 136, and/or another downhole components of the tube string 40 to one or more up hole components of the offshore system 10, such as the controller 108, a subsea interface card 148, or another component of the control system 120. The cable 140 may deliver power to the one or more
downhole components and/or telemetry to enable control of the downhole components, such as the passage isolation device 84. In this way, the number of downhole cables may be reduced, reducing the possibility of power and/or control cut off to the downhole components. For example, a single cable 140 may be coupled to, power, and provide communication between any number of downhole components, such as one or more of the passage isolation devices 84, one or more of the flow control valves 132, one or more additional components 136, and/or one or more other downhole components of the tube string 40. Additionally, by using electronic actuation, control, and communication with the passage isolation device 84 (e.g., electronic formation isolation valve), the passage isolation device 84 may have additional capabilities not possible with a mechanical or hydraulic actuated passage isolation device. For example, various sensor feedback or operational conditions of other downhole components may trigger actuation of the passage isolation device 84 in real-time in response to downhole conditions.
[0036] In some embodiments, the control system 120 may include one or more subsea or below sea level 44 control components. For example, the control system 120 may include one or more subsea module electronics, such as a subsea control module 144, the subsea interface card 148, and the wellhead 48 (e g., subsea Christmas tree). The subsea control module 144 and/or the subsea interface card 148 may be contained in a gas purged, 1-atm vessel mounted on a skid. External connections from the subsea control module 144 and/or the subsea interface card 148 may be via dry-mate connectors to a pressure-balanced oil filled enclosure that provides the secondary barrier to the subsea control module 144 and/or the subsea interface card 148 and includes connectors allowing the module frame to be retrieved independently from the other pump modules. The subsea components may communicate back to the controller 108 via fiber optic modems, 3rd party comms-on- power modems, or another suitable device. Communications between devices on the surface and subsea may be achieved over an Ethernet TCP/IP network managed by the Ethernet switches on the surface and subsea. In an embodiment, the one or more subsea components may provide downhole tools with power, such as Low-Power (LP) at 24VDC, or High-power (HP) at 270VDC.
[0037] FIGS. 3 and 4 are schematic cross-sectional side views of an embodiment of the passage isolation device 84 in accordance with one or more aspects of the present disclosure. FIG. 3 illustrates the passage isolation device 84 in a closed configuration 149 (e.g., isolated configuration) and FIG. 4 illustrates the passage isolation device 84 in an open configuration 150. As discussed above, at least a portion of the passage isolation device 84 may be disposed within the passage 76 of the tube string 40 to fluidly isolate one or more portions of the passage 76, providing a downhole barrier against pressure reversal, reduce formation damage, and minimize fluid loss. For example, the passage isolation device 84 may fluidly isolate or seal the first portion 88 (e.g., downhole portion, bottom portion) of the passage 76 including the first flow 92 of fluid (e.g., flow originating from the second producing layer 24, flow received by intake portion 80A) from the second portion 96 (e.g., up hole portion, upper portion) of the passage 76 including the second flow 100 of fluid (e.g., flow originating from the first producing layer 16, flow received by intake portion 80B).
[0038] The passage 76 of the tube string 40 may include or may be defined by a passage wall 152 (e.g., cylindrical wall, radial boundary, shell) defining the flow paths of the first flow 92 and/or the second flow 100. The tube string 40 and/or the passage isolation device 84 may also include a component housing 156 positioned external to the passage 76. The component housing 156 may be configured to contain or store one or more components of the tube string 40, such as a portion of the passage isolation device 84. In an embodiment, the component housing 156 may include an annulus 160 radially outward or on top of the passage 76 and/or the passage wall 152, relative to an axis 162 extending along the length of the tube string 40 and/or passage 76.
[0039] Although the passage isolation device 84 is discussed below as disposed within the tube string 40 or a part of the tube string 40 at one location, it will be appreciated that multiple passage isolation devices 84 may be disposed at various up hole and downhole positions of the tube string 40 to isolate multiple sections or portions of the passage 76. The passage isolation device 84 may include a ball valve 164 configured to regulate flow of fluid through the passage 76. In certain embodiments, the passage isolation device 84 may include any type of valve or valve element, such as a ball valve, a butterfly valve, a
gate valve, or any combination thereof. However, the ball valve 164 is one example of the valve for the passage isolation device 84. For example, the ball valve 164 may be actuated to enable the first flow 92 of fluid though the passage to mix or combine with the second flow 100 of fluid. To this end, the ball valve 164 may include a rotary ball 166 and a hole or orifice 168 (e.g., central bore or fluid passage) extending through the rotary ball 166 and configured to enable fluid flow when the ball valve 164 is in the open configuration 150 . In the open configuration 150, as shown in the illustrated embodiment of FIG. 4, the ball valve 164 may be positioned (e.g., rotated) to expose the orifice 168 to the passage 76, fluidly coupling the first portion 88 and the second portion 96 of the passage 76, enabling the first flow 92 through the passage isolation device 84. In the closed configuration 147, as shown in the illustrated embodiment of FIG. 3, the ball valve 164 may be positioned (e.g., rotated) to block the orifice 168 (e.g., with the passage wall 152), isolating the first portion 88 and the second portion 96 of the passage 76, disabling the first flow 92 through the passage isolation device 84. The ball valve 164 may be configured to rotate against a dynamic sealing system energized by a differential pressure above (e.g., up hole) and below (e g., downhole) the ball valve 164. In an embodiment, ball valve 164 may be configured for bi-directional pressure sealing within the passage 76.
[0040] The passage isolation device 84 may include a mandrel 172 (e.g., tube section, annular body, or sleeve having a central bore or fluid passage) configured to translate in a linear or axial direction, relative to the axis 162, to engage or actuate the ball valve 164. The mandrel 172 may be disposed within (e.g., radially within) the passage 76, around (e.g., radially around) the passage 76, and/or may be incorporated as a portion of the passage 76. The mandrel 172 may be configured to move or translate axially relative to one or more components of the tube string 40 to actuate the ball valve 164, enabling or disabling fluid flow. That is, the passage isolation device 84 may translate linear or axial movement of the mandrel 172 into rotational movement of the ball valve 164 to fluidly couple or isolate respective portions of the passage 76. For example, the mandrel 172 may be configured to translate axially or linearly, relative to the axis 162, to engage or disengage a yoke 176 rotationally coupled to the ball valve 164. Referring to FIG. 3, the mandrel 172 may translate in a first axial direction 180, relative to the axis 162, to engage the yoke 176. The yoke 176 may transfer the axial or linear force of the mandrel 172 into rotational force
to move or rotate the ball valve 164 in a first rotational direction 182 (e.g., clockwise), exposing the orifice 168 to the passage 76 and fluidly coupling the first portion 88 and the second portion 96 of the passage 76. In an embodiment, the yoke 176 may include an arm 177 (e.g., join arm) coupled or pinned to a joint 178 of the ball valve 164 (e.g., rotary ball 166of the ball valve 164) that is off center from a rotational axis of the ball valve 164. Axial movement of the arm 177 coupled to the joint 178 may translate the axial movement into a rotational movement of the ball valve 164.
[0041] Referring now to FIG. 4, to close the ball valve 164, the mandrel 172 may translate in a second axial direction 188, opposite of the first axial direction 180, relative to the axis 162, to disengage the yoke 176. The yoke 176 may rotate the ball valve 164 in a second rotational direction 192, blocking the orifice 168 and isolating the first portion 88 and the second portion 96 of the passage 76. In an embodiment, the yoke 176 and/or the ball valve 164 may be acted on by an additional force (e.g., spring force via one or more springs), where in the absence of the engagement of the mandrel 172, the ball valve 164 may be acted on by the additional force to rotate the ball valve 164(e.g., rotate back to a starting position).
[0042] Although the actuation (e.g., opening and closing) of the passage isolation device 84 is discussed with regards certain directions (e.g., first axial direction 180, second axial direction 188, first rotational direction 182, second rotational direction 192), it will be appreciated that other movements of components of the passage isolation device 84 are contemplated to actuate the ball valve 164. For example, in some embodiments, the mandrel 172 may translate in the second axial direction to engage the ball valve 164 and expose the orifice 168 of the passage 76. Additionally, the ball valve 164 may rotate in the second rotational direction to expose the orifice 168 of the passage 76.
[0043] In some embodiments, the passage isolation device 84 may be an electronic passage isolation device, configured to electronically actuate the ball valve 164 to regulate flow of fluid in the passage 76 in a manner as discussed above. For example, the passage isolation device 84 may include an actuator 196 (e.g., electronic actuator, electromechanical actuator, downhole actuator) configured to translate an axial linkage (e.g., a shaft and/or a piston 200) coupled to the mandrel 172 along the axial directions
180, 188 to engage or disengage the ball valve 164 In the illustrated embodiment, the piston 200 is disposed in a cylinder on one radial side of the passage isolation device 84. The piston 200 may be coupled to the mandrel 172 by any suitable attachment mechanism, for example, through friction fit, one or more fasteners, and/or chemical adhesives. In an embodiment, the piston 200 may be coupled to the mandrel 172 via a connector 204 (e.g., radial connector or arm). In an embodiment, the piston 200 may extend (e.g., axially extend relative to the axis 162) through the component housing 156. In some embodiments, the connector 204 may extend from the component housing 156 to the mandrel 172 through a component housing wall 198 via a passage aperture 208 (e.g., axial slot). During actuation, the connector 204 may translate axially within the passage aperture 208 to translate the mandrel 172 in an axial direction, thereby engaging and disengaging the ball valve 164 in the axial direction.
[0044] The actuator 196 may be disposed external or internal of the tube string 40 and may be disposed at various locations of depths of the tube string 40. For example, the actuator 196 may be positioned outside of the passage 76, within the component housing 156 or another cavity or containment area (e.g., hermetically seal housing) of the tube string 40. In an embodiment, at least a portion of the actuator may straddle a body (e.g., outer shell) of the passage isolation device 84. To adjust or translate the mandrel 172 and engage/di sengage the ball valve 164, the actuator 196 may include an electric motor or drive 212 (e.g., DC brushless motor, downhole motor) coupled to the piston 200, configured to translate (e.g., extend, retract) the piston 200 along the axial directions 180, 188, to translate the mandrel 172. In certain embodiments, the electric drive 212 may be a linear motor configured to convert electrical power into a linear motion of the piston 200. In some embodiments, the electric drive 212 may convert a torque and rotation of the electric drive 212 into linear motion through a gearbox and/or a rotary /linear converter, such as a ball screw mechanism. In certain embodiments, the electric drive 212 may include an electric motor (e.g., DC brushless motor) that rotates a shaft having external threads (e.g., male threaded shaft) relative to a linearly movable body having internal threads (e.g., female threaded body), thereby converting rotational motion of the electric motor into linear motion of the linearly movable body coupled to the piston 200. In certain embodiments, the electric drive 212 may include an electric motor coupled to a gear box,
assembly, or transmission, which is configured to convert the rotational motion of the electric motor into linear motion of the piston 200. For example, the gear assembly may include a planetary gear assembly having a sun gear, a plurality of planet gears disposed about the sun gear, and a ring gear disposed about the plurality of planet gears. By further example, the gear assembly may include a rack and pinion assembly having a circular gear or pinion driven to rotate by the electric motor, while the pinion rotates along a linear gear or rack to convert the rotational motion of the pinion into linear motion of the rack. In some embodiments, the electric drive 212 may receive power (e.g., electrical power) from an above ground location via, for example, the cable 140. In some embodiments, the electric drive 212 may receive power (e.g., electrical power) from a below ground location, such as a battery.
[0045] In some embodiments, the actuator 154 may include a controller 216 (e.g., downhole controller or control module) configured to perform one or more downhole operations based on one or more inputs. For example, the controller 216 may send a signal (e.g., first signal) to the electric drive 212 to actuate the ball valve 164 to the closed configuration 149 (e.g., isolating position) based on a detected parameter, a signal received from an above ground source (e.g., controller 108, human operator), and/or a signal received from a below ground source (e.g., other controllers of the tube string 40). For instance, the controller 216 may instruct the electric drive 212 to actuate the ball valve 164 to the closed configuration 149 in response an up hole signal (e.g., from the controller 108) indicative of a desire isolate a portion of the passage 76, for example, during a maintenance check of the sealing performance of the ball valve 164. The controller 216 may further send a signal to the electric drive 212 to actuate the ball valve 164 to the open configuration 150 based on a detected parameter, a signal from an above ground source, and/or a signal from a below ground source. By enabling electronic actuation of the passage isolation device 84, fluid flow may be isolated within the passage 76 more frequently, compared to traditional isolation valves (e.g., mechanical valves). In this way, work over events that use isolated portions of the passage 76 may be performed more frequently and in a more expedited manner.
[0046] In an embodiment, the tube string 40 may include one or more sensors positioned external or internal to the tube string 40 and configured to detect or monitor one or more parameters. For example, the tube string 40 may include one or more sensors configured to detect a parameter (e.g., pressure, temperature, flow rate) of the fluid within the tube string 40 (e.g., within the passage 76) and/or external to the tube string 40 (e.g., within the open hole 32.) Additionally or alternatively the one or more sensors may be configured to monitor or detect one or more parameters associated with a component or tool of the tube string 40, such as a motor speed. In response to receiving a signal, data, or feedback from the one or more sensors, the controller 216 or the controller 108 may instruct (e.g., automatically instruct, instruct in real-time) the electric drive 212 to actuate the ball valve 164 to the closed configuration 149 or the open configuration, based on the feedback.
[0047] In an embodiment, the actuator 196 may include a compensation system 218 (e g., pressure and/or volume compensation system) configured to compensate or balance an internal volume of the actuator 196 during actuation. For example, the compensation system 218 may be configured to maintain a pressure, volume, and/or stability within the actuator 196 during actuation to reduce damage to other components of the actuator 196. In one embodiment, the compensation system 218 may include one or more metallic bellows filled with di-electric oil, one or more pistons, one or more diaphragms, and so forth. Additionally or alternatively, one or more components of the actuator 196 may be assembled onto a chassis within the tube string 40.
[0048] FIG. 5 is a cross-sectional side view of an embodiment of the passage isolation device 84 in accordance with one or more aspects of the present disclosure. As discussed above, the passage isolation device 84 may include the ball valve 164 disposed within the passage 76 of the tube string 40. The actuator 196 (shown in FIGS. 3 and 4) may actuate the piston 200 to translate the mandrel 172 to engage the yoke 176 coupled or pinned to the ball valve 164 to engage and disengage the ball valve 164, fluidly coupling or isolating portions of the passage 76. In an embodiment, the tube string 40 may include a collet 220 configured to translate in the first axial direction 180 or the second axial direction 188 within the tube string 40. In some instances, the collet 220 may translate between two axial positions, a first position associated with the closed configuration 149 and a second
position associated with the open configuration 150 of the passage isolation device 84. In the two positions, the collet 220 may engage with another component of the tube string 40 to lock or maintain a position of the ball valve 164 in the respective configuration. In some embodiments, the collet 220 may be configured to manually actuate the ball valve 164 to regulate fluid flow as an override and/or emergency feature in addition to electronic actuation of the ball valve 164 during normal operation. For example, during a malfunction, breakdown, or other deleterious event (e.g., valve failure scenario), an intervention shifting tool may engage with the collet 220 to disconnect the connector 204 from the mandrel 172, disconnecting the actuator 196 and piston 200 from the mandrel 172 and the ball valve 164. Once disconnected, an axial shift of the collet 220 may rotate the ball valve 164 into the closed configuration 149 or the open configuration 150. The intervention shifting tool may be used to open or close the ball valve 164, even under differential pressure or high-loss conditions. The intervention shifting tool may be run down the tube string 40 (e.g., within the passage 76), and the intervention shifting tool's shifting profile may be designed to minimize risk of interference or engagement with profiles of other completion technologies (e.g., other downhole tools of the tube string 40). When the intervention shifting tool passes through the collet 220, it engages a shifting profile of the collet 220, actuating the ball valve 164 and creating a gas-tight seal or opening the ball valve 164. After actuation, the intervention shifting tool may be retrieved from a downhole location.
[0049] FIG. 6 is a cross-sectional side view of an embodiment of the passage isolation device 84 in accordance with one or more aspects of the present disclosure. In some embodiments, the connector 204 of the passage isolation device 84 may include one or more shear member or tabs 224 that connects the piston 200 and actuator 196 to the mandrel 172. In certain situations, such as a valve failure, the tab may be sheared or disconnected, freeing the mandrel 172 from the actuator 196 and enabling manual movement of the mandrel 172 and the ball valve 164 via the collet 220 and the intervention shifting tool. For example, the mandrel 172 may be translated in the second axial direction 188, via the intervention from the collet 220 and the intervention shifting tool, causing the connector 204 to abut the passage wall 152. Further movement of the mandrel 172 in the direction
188 imparts a force (e.g., shear force) on the tab 224, shearing or disconnecting the tab 224 from the connector 204.
[0050] FIG. 7 is a perspective view of an embodiment of the ball valve 164 that may be used in the passage isolation device 84 to regulate fluid flow in accordance with one or more aspects of the present disclosure. As discussed above, the ball valve 164 may include the orifice 168 extending through the ball valve 164 and configured to enable fluid flow through the ball valve 164 during the open configuration 150, as illustrated here. To isolate sections or portions or the passage 76, the ball valve 164 may rotate to block flow through the orifice 168. For example, the ball valve 164 may be rotationally coupled (e.g., pinned) to a support structure 230 which may include a pair of U-shaped tip portions 234 rotationally coupled to a pair of protrusions 228 (e.g., cylindrical protrusions, pins, or shaft portions) extending radially from diametrically opposite sides of the ball valve 164.
[0051] FIGS. 8 and 9 are schematics of embodiments of the tube string 40 that may be used to produce fluid from the geological formation 12, in accordance with one or more embodiments of the present disclosure. The tube string 40 may include various configurations for components, including the one or more intake portions 80, the one or more wellbore isolation devices 64, and/or the one or more passage isolation devices 84.
[0052] Technical effects of the disclosed embodiments enable electronic actuation of one or more passage isolation devices 84 (e.g., electronic formation isolation valve) using a single umbilical. The electronic actuation of may be achieved with an electronic actuator configured to actuate a valve (e.g., a ball valve) between open and closed positions for isolation of various regions in a wellbore and/or formation zones. Advantageously, the electronic actuation of the one or more passage isolation devices 84 enables a simpler and less time consuming operation as compared with mechanical or hydraulic actuation of the passage isolation devices 84. For example, the electronic actuation of the one or more passage isolation devices 84 may be performed on the fly in real-time, thereby enabling quicker isolations as needed for various operations (e.g., maintenance, wellbore measurements, or other procedures). As a result, the various operations may be performed more frequently in the wellbore, resulting in more frequent measurements, more frequent maintenance and possibly less problems with equipment, and reducing the risk of
catastrophic failures. For at least these reasons, the disclosed embodiments improve the efficiency and performance of various equipment at a wellsite.
