Abstract: A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.

Abstract: A technique facilitates monitoring of load forces at various locations along a well string. The technique enables determination of loading based on measurement of hydraulic pressures, and the technique may be used to determine axial loading along a variety of downhole completions. A compensating piston may be disposed in a fluid chamber between a housing and a mandrel of one of the completions. The mandrel is slidably received in the housing and the fluid chamber is coupled with a sensor gauge via a pressure communication passage to facilitate accurate measurement of loading via the hydraulic pressures in the fluid chamber. The load forces may be monitored during, for example, landing of an uphole completion into a downhole completion. The sensor gauge also may be used for monitoring other pressures along the overall completion.

Abstract: A technique facilitates joining of an upper completion with a lower completion in a manner which enables adjustability. According to an embodiment, an assembly may be used to join the upper completion to the lower completion for joint deployment downhole into a wellbore. However, the assembly is constructed to provide adjustability for accommodating various conditions which may occur downhole. For example, the assembly may be actuatable to enable release of the upper completion and/or contraction to adjust positioning of the upper completion

Abstract: Wireless multi-stage completions for providing power to and telemetry communication with downhole device(s) are provided. A power generation system can be disposed along a production string to power downhole devices. The power generation system can be driven by annulus fluid flow or production fluid flow and converts the fluid flow to electrical energy. The power generation system can be retrievably disposed in a side pocket mandrel.

Abstract: A technique facilitates injection via an injector well while providing automatic restriction of unwanted back flow. A completion positioned in a borehole facilitates the injection operation. The completion includes a packer coupled with a tubing and oriented to enable formation of a seal between the tubing and a surrounding casing. A formation isolation valve is coupled to the tubing. Additionally, a mechanical assembly is coupled to the tubing at, for example, a location below the formation isolation valve. The mechanical assembly may include a mechanical formation isolation valve and a flow controller. The flow controller is automatically actuatable to enable a flow of injection fluid in a downhole direction while blocking fluid flow in an uphole direction while the mechanical formation isolation valve is in a closed position. The flow controller includes a plurality of flow restrictors positioned to control flow between an interior and an exterior of the tubing.

Abstract: An actuator assembly for effective interventionless activation of a valve in wells of multilateral architecture. The assembly may be pressure actuated from an oilfield surface even in certain circumstances where another valve in another leg of the well has been opened in a manner compromising pressure control of the well. Due to the multi-stage nature of the actuator, pressure based activation remains viable as a result of supplemental and/or fail-safe modes of actuation, for example, where such pressure control becomes compromised.

Abstract: A technique facilitates controlled injection of a chemical injection fluid at a desired downhole location. A chemical injection valve is mounted along a well tubing and is disposed externally of an internal flow passage through the well tubing. The chemical injection valve is operated via hydraulic pressure which is applied to actuate the chemical injection valve between closed flow and open flow positions. The chemical injection valve controls flow of the chemical injection fluid to at least one injection port. The at least one injection port may be positioned to inject the chemical injection fluid into the internal flow passage of the well tubing.

Abstract: A technique facilitates injection, e.g. water injection, via an injector well while providing automatic restriction of unwanted back flow. A completion may be positioned in a borehole to facilitate the injection operation. The completion comprises a packer coupled with a tubing and oriented to enable formation of a seal between the tubing and a surrounding casing. A flow isolation valve is coupled to the tubing for control of fluid flow along the tubing. Additionally, a mechanical assembly is coupled to the tubing at, for example, a location below the formation isolation valve. The mechanical assembly may comprise a tubing closure member, e.g. a mechanical formation isolation valve or a nipple and plug assembly, and a flow controller. The flow controller is automatically actuatable to enable a flow of injection fluid in a downhole direction while blocking fluid flow in an uphole direction while the tubing closure member is in a closed position.

Abstract: A technique combines a wireless coupler system with casing to communicate signals from and/or to a device external to the casing. The wireless coupler system may comprise an inductive coupler system formed with a female inductive coupler disposed along an exterior of the well casing and a male inductive coupler mounted along tubing disposed within the well casing. The female inductive coupler is operatively coupled with the sensor and the male inductive coupler is operatively coupled with a communication line routed along the tubing. The inductive coupler system is constructed to facilitate alignment of the male inductive coupler with the female inductive coupler as the tubing is moved along an interior of the well casing. Additionally, the inductive coupler system may be constructed with a bypass channel to facilitate the flow of fluid and routing of communication lines through the inductive coupler system.
