摘要： A valve assembly for integration within a wellbore string is provided. The valve assembly has a valve housing with a housing port, a bottom sleeve mounted and slidable within the valve housing between closed and open positions, and a top sleeve mounted within the valve housing and defining an annular region therebetween. The top sleeve has a sleeve port and is slidable within the valve housing between a first position where the top sleeve engages the valve housing and defines an annular chamber within the annular region, and a production position where the sleeve port is in fluid communication with the housing port to define a fluid pathway along which fluids flow from the reservoir through the annular chamber. While in the first position, the annular chamber has an inlet allowing fluid to flow into and pressurize the annular chamber to prevent particulates from flowing into the annular region.

摘要： A method of fault detection and recovery in a tubing string located in a hydrocarbon well, a method of fault protection in a tubing string located in a hydrocarbon well, and an apparatus and system for same. In one aspect, there is provided a method of fault detection and recovery in a tubing string located in a hydrocarbon well, the tubing string having a plurality of valves, each valve having a control unit, each control unit being connected in series to a power-line providing power and communication, each of the control units being independently controllable. The method comprises: detecting a short circuit, fault or failure in one of the control units of the tubing string via an output of the power-line; causing individual control units to be selectively isolated from the power-line via a circuit interrupting device; and determining one or more control unit associated with the short circuit, fault or failure via the output of the power-line while individual control units are selectively isolated from the power-line.

摘要： An apparatus and a method of controlling flow communication with an apparatus are disclosed. The apparatus includes a flow communicator, a flow control member, an uphole-disposed flow interference effector uphole of the flow communicator, and a downhole-disposed flow interference effector downhole of the flow communicator. While each of the uphole-disposed flow interference effector and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, the flow communicator is closed. Displacement of the flow control member, relative to the flow communicator, in the downhole direction, opens the flow communicator. While there is an absence of occlusion of the second uphole-disposed flow interference-effecting member of the uphole-disposed flow interference effector, the flow control member is disposable, relative to the flow communicator, such that each one of the second-uphole disposed flow interference-effecting member and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, such that the flow communicator is closed.

摘要： A flow control apparatus for producing hydrocarbon material from a subterranean formation is disclosed. The apparatus includes a housing that defines a housing passage, and a flow communicator that extends through the housing for effecting fluid communication between the housing passage and the subterranean formation. The apparatus includes a flow controller within the housing for modulating flow communication between the housing passage and the subterranean formation via the flow communicator. The flow controller includes a filter medium-defining counterpart and a shroud-defining counterpart, and the filter medium-defining counterpart has a filter medium. The flow controller is configurable for disposition relative to the flow communicator to open, close, or screen the flow communicator. While the filter medium and the flow communicator are not aligned, the housing and shroud-defining counterpart shields the filter medium from the housing passage and the external environment.

摘要： A valve assembly for integration within a wellbore string disposed within a subterranean reservoir is provided. The valve assembly includes a valve housing having one or more injection ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a valve sleeve operatively mounted within the valve housing and comprising a fluid channel adapted to establish fluid communication between the central passage and the injection ports, and configured to create a fluid flowrate restriction. The valve assembly has a flow adjuster connectable to the valve sleeve, and is selectively arranged to align an opening with the fluid channel and allow fluid to flow from the fluid channel through the opening to the injection port, wherein connecting the flow adjuster to the valve sleeve defines a flow length of the fluid channel to adjust the fluid restriction created by the fluid channel.

摘要： A wellbore apparatus to control the flow of fluids into the wellbore, comprising: a housing; a passage disposed within the housing; a flow communicator for allowing communication into the passage; a flow control member; and frangible members releasably retaining the flow control member to the housing in a retained position, and configured, while the apparatus is disposed in an operative orientation, for becoming fractured in response to application of a force in a downhole direction to release the flow control member from the housing such that the flow control member becomes displaceable relative to the flow communicator; wherein: the flow communicator and the flow control member are configured such that, while the apparatus is disposed in the operative orientation within the wellbore, the flow control member is disposed uphole relative to the retained position while the flow communicator is disposed in the open condition.

摘要： Oil recovery can include providing a tubing string and isolation devices to define isolated intervals for an existing well previously operated using plug-and-perf and primary production. Valve assemblies are installed in respective isolated intervals, each valve assembly including at least two valves. The valve can be operated in open and closed configurations, and at least one open configuration provides choked flow via an elongated passage. The valves can have a housing and a shiftable sleeve. The valve assemblies can be operated to provide a desired openness based on the injectivity or other properties by shifting the sleeves of the valves. Different flow resistance levels can be provided to facilitate enhanced operations for water flooding and other oil recovery processes.

摘要： There is provided a flow control apparatus including a housing, a port, a flow control member, a sensor, and a trigger. The housing includes a housing passage. The port extends through the housing. The flow control member includes a fluid responsive surface, and is configured for displacement, relative to the port, such that fluid communication is effected between the port and the housing passage. The sensor is coupled to the housing for sensing an actuating signal. The trigger is configured for effecting fluid communication between the housing passage and the fluid responsive surface, in response to the sensing of an actuating signal by the sensor, for effecting displacement of the flow control member.
