For oil and gas exploration and production, a network of wells, installations and other conduits may be established by connecting sections of metal pipe together. For example, a well installation may be completed, in part, by lowering multiple sections of metal pipe (i.e., a casing string) into a wellbore, and cementing the casing string in place. In some well installations, multiple casing strings are employed (e.g., a concentric multi-string arrangement) to allow for different operations related to well completion, production, or enhanced oil recovery (EOR) options.
During production operations, different tools may be disposed downhole on production tubing to control the flow of desirable fluids from a formation. In examples, downhole tools may have valves that actuate using pistons. Currently, these pistons may be hydraulically operated with hydraulic lines that may stretch from the surface to the downhole tool disposed in a formation. Due to the extreme nature experienced downhole, hydraulic lines may be susceptible to failure and may not operate correctly. Additionally, each line may take up valuable space within a wellbore, which may limit the number of tools an operator may dispose downhole
These drawings illustrate certain aspects of some examples of the present disclosure and should not be used to limit or define the disclosure.
Systems and methods discussed below may be directed to a downhole device that may operate and/or function from pressure applied to an annulus of a wellbore. Specifically, a downhole device sensitive to pressure cycles, which may allow the downhole device to function during operations at specified times.
In examples, wellbore 102 may be cased with casing string 118. As illustrated, casing string 118 may include a first casing 120 and a second casing 122. However, casing string 118 may include any suitable number of casings. Each casing may include one or more casing segments 124. Casing segments 124 help maintain the structure of wellbore 102 and prevent wellbore 102 from collapsing in on itself. As illustrated, production tubing 112 may be positioned inside of casing string 122 extending part of the distance down wellbore 102. Production tubing 112 may include concentric pipes formed from casing segments 124, which may be attached to each other by collars 126. In some examples, a portion of the well may not be cased and may be referred to as “open hole.” The space between production tubing 112 and casing segments 124 or wellbore wall 128 may be an annulus 130. Production fluid may enter annulus 130 from formation 104 and then may enter production tubing 112 from annulus 130. Production tubing 112 may carry production fluid uphole to production tree 106. Production fluid may then be delivered to various surface facilities for processing via a surface pipeline 132.
The flow of production fluid through production tubing 112 may be controlled by barrier valve 200, further discussed below. During operation, barrier valve 200 may function in an “open” state or a “closed” state. The “open” state allows for the movement of production fluid through production tubing 112 and the “closed” state prevents the movement of production fluid through production tubing 112. Without limitation, actuation module 134 may be attached to barrier valve 200 and may function to control the opening or closing of barrier valve 200.
As discussed below, an actuation module 134 may be disposed in production tubing 112. In examples, actuation module 134 may work within production fluid recovery system 100 to control flow of production fluid within production tubing 112. Additionally, actuation module 134 may operate with a plurality of actuation modules 134 to segment wellbore 102 into different identified areas. Currently, actuation module 134 may operate through the use of hydraulic lines (not illustrated) connected to actuation module 134. These hydraulic lines may be controlled by an information handling system 136 through communication line 138. Communication line 138 may be any suitable wire communications and/or wireless communications.
Information handling system 136 may include any instrumentality or aggregate of instrumentalities operable to compute, estimate, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, information handling system 136 may be a personal computer 140, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. Information handling system 136 may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of information handling system 136 may include one or more disk drives, one or more network ports for communication with external devices as well as various input and output (I/O) devices, such as a keyboard 142, a mouse, and a video display 144. Information handling system 136 may also include one or more buses operable to transmit communications between the various hardware components.
Alternatively, systems and methods of the present disclosure may be implemented, at least in part, with non-transitory computer-readable media. Non-transitory computer-readable media may include any instrumentality or aggregation of instrumentalities that may retain data and/or instructions for a period of time. Non-transitory computer-readable media may include, for example, without limitation, storage media such as a direct access storage device 146 (e.g., a hard disk drive or floppy disk drive), a sequential access storage device (e.g., a tape disk drive), compact disk, CD-ROM, DVD, RAM, ROM, electrically erasable programmable read-only memory (EEPROM), and/or flash memory; as well as communications media such wires, optical fibers, microwaves, radio waves, and other electromagnetic and/or optical carriers; and/or any combination of the foregoing.
As mentioned above, current technology may control actuation module 134 through a direct hydraulic connection, which may be controlled by information handling system 136. Discussed below,
The number of cycles to increase pressure and release pressure may be pre-determined and may be about one cycle to about five cycles, about two cycles to about six cycles, about three cycles to about ten cycles, about ten cycles to about fifteen cycles, about ten cycles to about twenty cycles, about ten cycles to about twenty-four cycle, or about twenty cycles to about twenty-five cycles. Without limitation, as described above, pressure cycles may increase pressure within production fluid recovery system 100 through annulus 130, production tubing 112, and/or any combination thereof. Additionally, without limitation, pressure may be released from production fluid recovery system 100 through production tubing 112.
As illustrated in
In examples, mechanism 202 may include a pair of arms 216 and members 218. Members 218 may include apertures 220 and a raised rim 222 extending from an inner surface 224. Each arm 216 may be disposed in a plane that is parallel with respective planar surfaces 208. Cylindrical projections 210 extend through slots 226 formed through each of arms 216 and are received into apertures 220. Raised rims 222 may also extend into slots 226. Thus, arms 216 may be sandwiched between members 218 and ball 204. Raised rims 222 may be retained in slots 226 such that arms 216 may be permitted to slide in a direction parallel to the X-axis but are prevented from moving in a direction parallel to the Z-axis. Actuation pins 228 may be provided on an inner surface 230 of each arm 216. Actuation pins 228 may be received into radial grooves 212 formed in ball 204. A bearing may be positioned between each pin 228 and radial groove 212. A bearing may also be positioned between each cylindrical projection 210 and raised rims 222.
In an open position, radial grooves 212 may be angularly positioned so that the internal bore 232 of ball 204 at least partially aligns with the first and second bore portions 234, 236 so as to provide fluid communication through barrier valve 200. In a closed position, ball 204 may be pivoted about the Y-axis until internal bore 232 of ball 204 may not provide fluid communication between the first and second bore portions 234, 236, thereby preventing fluid communication through barrier valve 200. Ball 204 may be rotated between the open and closed positions, thereby opening and closing barrier valve 200, by longitudinally displacing mechanism 202 relative to ball 204 in a direction parallel with the X-axis. As mechanism 202 is moved relative to ball 204, actuation pins 228 slide within radial grooves 212, causing ball 204 to pivot.
Barrier valve 200 may be opened or closed in any number of ways. For example, in some implementations, barrier valve 200 may be actuated by shifting a mandrel, disclosed below, in a longitudinal direction of the valve, e.g., a direction aligned with an axial direction of the first or second bore portions 234, 236, to rotate ball 204 into one of an open or closed position. In some instances, the mandrel may be shifted by application of a mechanical force transferred to the mandrel through a secondary tool. It should also be noted that barrier valve 200 may be replaced by a sliding sleeve. In other implementations, barrier valve 200 may be opened by application of fluid pressure. For example, fluid pressure may be applied to a ball 204 in a closed position. The fluid pressure may actuate a secondary mechanism that releases a biasing element, such as a spring, to pivot the ball 204 into an open position.
As illustrated in
With continued reference to
To assist in this operation, actuation module 134 may be activated by supplying a volume of fluid into second hydraulic chamber 318, which may be in a “closed” position. Moving fluid into second hydraulic chamber 318 may push second piston 306, which is attached to mandrel 302, and mandrel 302 further into housing 300. It should be noted that first piston 304, which is the “open” position, is independent on mandrel 302 and may allow mandrel 302 to slide below first piston 304 without moving. Vent port 314 may allow fluid to continue to move as mandrel 302 moves, which may prevent a hydraulic “lock.”
In examples, at least one liquid spring cartridge or mechanism (not illustrated) may be used during operations. For the sake of brevity, it should be noted that the use of “liquid spring cartridge” also encompasses the use of a “liquid spring mechanism.” The liquid spring cartridge may activate any downhole tool that may use a piston. For example, a first liquid spring cartridge may open the downhole tool and a second liquid spring cartridge may close the downhole tool. It should be noted that the downhole tool may be sliding side doors, mandrels, sleeves, valves, and/or the like.
During operations described above, one or more liquid spring cartridges may function to operate ball 304 (e.g., referring to
For each pressure cycles within annulus 130 the first liquid spring cartridge moves a predetermined increment of about 0.3 inch to about 0.5 inch (about 0.7 cm to about 1.25 cm). During operation, after a pre-determined number of pressure cycle, for example about 10 pressure cycles, the first liquid spring cartridge may free a first plug which may moves a second plug that may allow communication from annulus 130 to first piston chamber 316 and/or second piston chamber 318 (e.g., referring got
