ELECTRONIC RUPTURE DISC WITH ATMOSPHERIC CHAMBER

CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present document is based on and claims priority to U.S. Provisional Patent Application Serial No. 62/978,154, filed February 18, 2020, which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] In a variety of well related applications, downhole tools are actuated to perform desired functions. For example, packers, valves, and other downhole tools may be selectively actuated at specific times during a downhole procedure and/or at specific locations within a wellbore. Several types of mechanisms have been employed to enable actuation of the tool at the desired time and/or location.

[0003] For example, rupture discs have been employed to control actuation of one or more downhole tools. Rupture discs avoid premature actuation of the downhole tool before a predetermined level of pressure is applied. Once sufficient pressure is applied, the disc ruptures, which allows fluid pressure to facilitate activation of the downhole tool. There is a need for such rupture discs to be included in an actuation system having a portable and modular design to allow assembly of the actuation system into multiple housings on a variety of downhole tools.

[0017] In the following description, numerous details are set forth to provide an understanding of some embodiments of the present disclosure. However, it will be understood by those of ordinary skill in the art that that embodiments of the present disclosure may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.

[0018] In the specification and appended claims, the terms “connect,” “connection,” “connected,” “in connection with,” and “connecting,” are used to mean “in direct connection with,” in connection with via one or more elements.” The terms “couple,” “coupled,” “coupled with,” “coupled together,” and “coupling” are used to mean “directly coupled together,” or “coupled together via one or more elements.” The term “set” is used to mean setting “one element” or “more than one element.” As used herein, the terms “up” and “down,” “upper” and “lower,” “upwardly” and “downwardly,” “upstream” and “downstream,” “uphole” and “downhole,” “above” and “below,” “top” and “bottom,” and other like terms indicating relative positions above or below a given point or element are used in this description to more clearly describe some embodiments of the disclosure. Commonly, these terms relate to a reference point at the surface from which drilling operations are initiated as being the top point and the total depth being the lowest point, wherein the well (e.g., wellbore, borehole) is vertical, horizontal, or slanted relative to the surface.

[0019] One or more embodiments of the present disclosure include systems and methods for electronically triggering the actuation of at least one downhole device. The electronic trigger system according to one or more embodiments of the present disclosure may be a universal electronic trigger system that facilitates adding electronic actuation to any component in the oil field. In operation, a signal may be sent from surface or from a downhole signal emitter to the electronic trigger system according to one or more embodiments of the present disclosure to create downhole movement required to set, actuate, or release at least one downhole tool. Further, the electronic trigger system according to one or more embodiments of the present disclosure may assume a modular design to facilitate the assembly of the electronic trigger system into multiple housings on different oil field tools. These oil field tools could be assets, such as running tools used to deploy a liner hanger, for example, that are designed to return back to the surface between jobs. The electronic trigger system according to one or more embodiments of the present disclosure may include products for a one-time use system. In one or more embodiments of the present disclosure, most of the electronics and housing of the electronic trigger system may be reused for future jobs to save costs. For example, according to one or more embodiments of the present disclosure, only the actuation device, e.g., the electronic rupture disc, and the on-board battery may be required to be changed between jobs. That is, when an asset is returned back to the surface between jobs, as previously described, the electronic trigger system according to one or more embodiments of the present disclosure may be retrofitted and reinstalled onto the returned asset after the on-board battery and the actuation device are replaced, as needed.

[0020] Referring generally to FIG. 1 A, a perspective view of an electronic trigger system 10 according to one or more embodiments of the present disclosure is shown. As shown, the electronic trigger system 10 may assume a tubular shape and may have a longitudinal housing 12 according to one or more embodiments of the present disclosure.

[0021] Referring now to FIG. IB, a cross-sectional view of an electronic trigger system 10 according to one or more embodiments of the present disclosure is shown. As shown, the longitudinal housing 12 of the electronic trigger system 10 may include a detection section 14, an electronics section 16, and an actuation section 18 disposed therein according to one or more embodiments of the present disclosure. [0022] Referring now to FIGS. 2 A - 2C, a layout of an electronic trigger system 10 according to one or more embodiments of the present disclosure is shown. For example, FIG. 2 A shows how a cross-sectional view of the electronic trigger system 10 according to one or more embodiments of the present disclosure may align with a corresponding perspective view of the electronic trigger system 10 according to one or more embodiments of the present disclosure. FIG. 2B shows a zoomed-in view of the detection section 14 of the electronic trigger system 10 according to one or more embodiments of the present disclosure. As shown in FIG. 2B, the detection section 14 of the electronic trigger system 10 may include a pressure transducer 20 or a pressure sensor, according to one or more embodiments of the present disclosure. In one or more embodiments of the present disclosure, the pressure sensor 20 is configured to receive a predetermined pressure signal 22. Advantageously, the pressure sensor 20 of the electronic trigger system 10 is configured to sense any pressure logic, even pressures as low as 100 psi, for example. In one or more embodiments of the present disclosure, the predetermined pressure signal may include a plurality of pressure pulses, for example. The pressure sensor 20 of the electronic trigger system 10 may receive the predetermined pressure signal 22 from a surface location according to one or more embodiments of the present disclosure. In other embodiments of the present disclosure, the pressure sensor 20 of the electronic trigger system 10 may receive the predetermined pressure signal 22 from a downhole signal emitter. In one or more embodiments of the present disclosure, the downhole signal emitter may be disposed on an adjacent downhole device, for example. While FIG. 2B shows a pressure sensor 20 that is configured to receive a predetermined pressure signal 22, the electronic trigger system 10 according to one or more embodiments of the present disclosure may include different sensors or detectors for sensing other types of signals including acoustic signals or electromagnetic telemetry signals, for example. In other embodiments of the present disclosure, such sensors or detectors may be wired to a permanent downhole gauge system, for example.

[0023] Referring back to FIG. IB and FIG. 2A, the electronic trigger system 10 according to one or more embodiments of the present disclosure includes an electronics section 16. According to one or more embodiments of the present disclosure, the electronics section 16 includes an electronic control board 24 having at least one battery disposed thereon to provide on board power for the electronic trigger system 16. According to one or more embodiments of the present disclosure, the electronic control board 24 may also include a processor for decoding pressure signals received, including the predetermined pressure signal 22, memory, and a capacitor bank to provide power to an actuation device of the electronic trigger system 10, as further described below.

[0024] Still referring to FIG. IB and FIG. 2A, the electronic trigger system 10 according to one or more embodiments of the present disclosure includes an actuation section 18. Referring now to FIG. 2C, the actuation section 18 includes a prefill chamber 26, a setting piston 28 disposed in the prefill chamber 26, an atmospheric chamber 30, and an actuation device 32, according to one or more embodiments of the present disclosure. While FIG. 2C shows that the actuation device 32 may be an electronic rupture disc according to one or more embodiments of the present disclosure, the actuation device 32 may also be a motor or solenoid, for example. Further, while FIG. 2C shows only one atmospheric chamber 30, the electronic trigger system 10 may include two or more atmospheric chambers 30 to facilitate alternating the direction of movement of one or more system components without departing from the scope of the present disclosure.

[0025] Referring now to FIG. 3, an electronic trigger system 10 sub-assembly in a run-in- hole configuration is shown according to one or more embodiments of the present disclosure. Specifically, FIG. 3 shows the actuation section 18 of the electronic trigger system 10 in the run -in-hole configuration. As shown in FIG. 3, the prefill chamber 26 of the actuation section 18 may be filled with a predetermined amount of prefilled fluid at hydrostatic pressure 27. According to one or more embodiments of the present disclosure, the predetermined amount of prefilled fluid at hydrostatic pressure 27 may be trapped between the setting piston 28 and the actuation device 32 in the prefill chamber 26. Moreover, according to one or more embodiments of the present disclosure, the actuation device 32 isolates the prefilled fluid at hydrostatic pressure 27 in the prefill chamber 26 from the atmospheric chamber 30. According to one or more embodiments of the present disclosure, the actuation section 18 of the electronic trigger system 10 may also include a pressure port. For example, FIG. 3 shows an active pressure path through the pressure port of the electronic trigger system 10 at arrow 33, according to one or more embodiments of the present disclosure. According to one or more embodiments of the present disclosure, the pressure port and the setting piston 28 may share a common seal bore. In one or more embodiments of the present disclosure, an inflow control device may be installed in the pressure port for restricting flow of fluid through the pressure port, for example. According to one or more embodiments of the present disclosure, the actuation section 18 of the electronic trigger system 10 may also include a plurality of seals 34 located in front of the atmospheric chamber 30.

[0026] Referring to FIGS. 2 A, 2B, 2C, and 3, actuation occurs when, upon receipt of the predetermined pressure signal 22 by the pressure sensor 20, the electronic control board 24 transmits power to the actuation device 32, causing the prefilled fluid 27 to flow through the actuation device 32 and into the at least one atmospheric chamber 30 using the pressure port, as previously described. According to one or more embodiments of the present disclosure, the flowing of the prefilled fluid 27 from the prefill chamber 26 into the at least one atmospheric chamber 30 causes the setting piston 28 to move linearly within the prefill chamber 26 toward the actuation device 32. That is, the push for movement of the setting piston 28 within the prefill chamber 26 is coming from the hydrostatic pressure fluid 27 along the active pressure path at arrow 33. For example, FIG. 4 shows an electronic trigger system 10 sub-assembly after actuation, according to one or more embodiments of the present disclosure. Indeed, as shown in FIG. 4, by the electronic control board 24 transmitting power to the actuation device 32, the actuation device 32 no longer isolates the prefilled fluid at hydrostatic pressure 27 in the prefill chamber 26 from the atmospheric chamber 30. As a result, the prefill fluid at hydrostatic pressure 27 within the prefill chamber 26 floods the atmospheric chamber 30. The transfer of prefill fluid 27 from the prefill chamber 26 into the atmospheric chamber 30 pulls the setting piston 28 to the left, creating the required movement to actuate the accompanying downhole tool, for example. As previously described, the electronic trigger system 10 may include two or more atmospheric chambers 30 to facilitate alternating the direction of movement of the setting piston 28 without departing from the scope of the present disclosure.

[0027] A system for use in a wellbore according to one or more embodiments of the present disclosure includes a completion having at least one downhole tool and the electronic trigger system 10, as previously described. According to one or more embodiments of the present disclosure, the longitudinal housing 12 of the electronic trigger system 10 may be coupled to the at least one downhole tool of the completion for actuation of the at least one downhole tool. Referring now to FIG. 5, the electronic trigger system 10 according to one or more embodiments of the present disclosure may be coupled to a hydrostatic packer 36 as the downhole tool, for example. According to one or more embodiments of the present disclosure, the electronic trigger system 10 coupled to the hydrostatic packer 36 may employ an electronic rupture disc as the actuation device 32 for remote activation of the hydrostatic packer 36, for example. According to one or more embodiments of the present disclosure, the longitudinal housing 12 of the electronic trigger system 10 is coupled to the hydrostatic packer 36 via an additional pressure line interface, for example. Advantageously, the pressure sensor 20 of the electronic trigger system 10 coupled to the hydrostatic packer 36 is configured to receive a predetermined pressure signal 22 that is specific for setting the hydrostatic packer 36. In this way, the system including the electronic trigger system 10 coupled to the hydrostatic packer 26 allows high pressure activities, such as fluid exchange with significant friction, without inadvertently activating the hydrostatic packer 36. Moreover, the system including electronic trigger system 10 coupled to the hydrostatic packer 26 may be a triple redundant system, according to one or more embodiments of the present disclosure. For example, as previously described, a specific pressure pulse logic or predetermined pressure signal 22 may be used to activate the electronic trigger system 10 to set the hydrostatic packer 36, according to one or more embodiments of the present disclosure. Alternatively, a pressure value may be used to rupture a burst disk to set the hydrostatic packer 36, or running a plug and applying additional pressure may enable hydraulic pressure fluid to set the hydrostatic packer 36, according to one or more embodiments of the present disclosure.

[0028] Referring now to FIG. 6, an electronic trigger system 10 according to one or more embodiments of the present disclosure may be coupled to a pressure actuatable circulation valve 38 as the downhole tool, for example. According to one or more embodiments of the present disclosure, the system including the electronic trigger system 10 coupled to the pressure actuatable circulation valve 38 may include a redundant electronic trigger system as a second activation mechanism to the electronic trigger system. [0029] According to one or more embodiments of the present disclosure, in the system including an electronic trigger system 10 coupled to the at least one downhole tool, the at least one downhole tool may include a pilot valve, for example. In such embodiments of the present disclosure, a stem portion of the setting piston 28 may be coupled to the pilot valve, and movement of the setting piston 28 may trigger an alternate path for pressure though the pilot valve to actuate the at least one downhole tool. According to one or more embodiments of the present disclosure, the at least one downhole tool may be an isolation valve including the pilot valve, for example.

[0030] Referring now to FIG. 7, a system for use in a wellbore according to one or more embodiments of the present disclosure may include a single trip completion 40 including at least one downhole tool including one or more of a packer, a sliding sleeve, and an isolation valve, for example, and an electronic trigger system 10 coupled to the at least one downhole tool in the single trip completion 40. One or more of the downhole tools of the single trip completion 40 may be equipped with the electronic trigger system 10 according to one or more embodiments of the present disclosure to simplify deployment and operation planning.

[0031] In a system for use in a wellbore according to one or more embodiments of the present disclosure, the system may include an electronic trigger system 10 coupled to at least one downhole tool. In one or more embodiments of the present disclosure, the prefill chamber 26 and the setting piston 28 may be disposed on the at least one downhole tool instead of being disposed in the electronic trigger system 10, for example. In such embodiments of the present disclosure, the prefill chamber 26 contains a predetermined about of prefilled fluid at hydrostatic pressure 27, and the setting piston 28 is disposed in the prefill chamber 26 such that the predetermined amount of prefilled fluid 27 biases the setting piston 28 in an initial position prior to actuation. Further, in such embodiments of the present disclosure, upon receipt of the predetermined pressure signal 22 by the pressure sensor 20, the electronic control board 24 of the electronic trigger system 10 transmits power to the actuation device 32, causing the prefilled fluid 27 in the prefill chamber 26 of the at least one downhole tool to flow through the actuation device of the electronic trigger system 10 and into the at least one atmospheric chamber 30, thereby actuating the at least one downhole tool.

[0032] Referring now to FIG. 8, a schematic for setting a packer using the electronic trigger system 10 according to one or more embodiments of the present disclosure is shown. As shown, in one or more embodiments of the present disclosure, a signal sent from surface may be detected by a pressure sensor 20, decoded on an electronic control board 24, and power from the electronic control board 24 may be transmitted to the actuation device 32 to facilitate setting the packer. As shown in FIG. 8, a communication channel may be created between the signal from surface, the pressure sensor 20, the electronic control board 24, the actuation device 32, and the downhole tool, according to one or more embodiments of the present disclosure. In addition to setting a downhole tool, the method according to one or more embodiments of the present disclosure may be implemented to actuate or release a downhole tool, for example.

[0033] The electronic trigger system according to one or more embodiments of the present disclosure may be split into multiple longitudinal housings, or tubes, to allow for easy maintenance or reduce the length requirement for installation. The electronic trigger system according to one or more embodiments of the present disclosure may be paired with an extension to create additional actuation without having to double the amount of electronics downhole. Such a configuration may be used to enable the closing and opening of a downhole device, or to actuate two or more devices. In one or more embodiments of the present disclosure, the system may include an additional electronic trigger system loaded into the same housing of a downhole device, or allowing the electronics to directly connect to multiple actuation devices, e.g., electronic rupture discs, for actuation. In one or more embodiments of the present disclosure, the longitudinal housing of the electronic trigger system may be simplified or may be a 3D printed housing to lower the cost and size of the components.

[0034] Although a few embodiments of the disclosure have been described in detail above, those of ordinary skill in the art will readily appreciate that many modifications are possible without materially departing from the teachings of this disclosure. Accordingly, such modifications are intended to be included within the scope of this disclosure as defined in the claims.
