    摘要: A system for use in a well includes plural flow control devices to control fluid flow in respective zones of the well, where each of at least some of the flow control devices includes a membrane having a permeable material to provide a flow restriction. The membranes of the at least some flow control devices have different permeabilities to provide corresponding different flow restrictions.

    摘要: A system that is usable with a subterranean well includes a first tubular member that is adapted to receive a flow of a first fluid. The system includes a second tubular member that is located in the flow and is substantially flexible to be moved by the flow to establish a pressure on a second fluid located inside the tubular member. A mechanism of the system uses this pressure to actuate a downhole tool.

    摘要: An apparatus that is usable with a well includes an power converter and a controller. The power converter translates electrical power into hydraulic power downhole in the well to generate a first hydraulic signal to cause a downhole tool to transition to a first state and a second hydraulic signal to cause the tool to transition to a different second state. The controller responds to stimuli that are communicated from the surface of the well to cause the actuator to generate one of the first and second hydraulic signals.

    摘要: A subsurface safety valve comprises a tubular body adapted for placement within a wellbore and defining a fluid passageway. A valve closure member, such as a flapper valve, is carried by the tubular body and movable through a closure path between positions opening and closing the fluid passageway. An actuator, such as a biasing spring, urges the valve closure member to its closing position. A flow tube is axially-movable within the tubular body between a first position preventing the actuator from urging the valve closure member to its closing position and a second position permitting the actuator to urge the valve closure member to its closing position. A latch assembly is provided for preventing movement of the valve closure member from its opening position to its closing position until the flow tube has been urged clear of the closure path. Aspects of the safety valve are employed by a related method and system.

    摘要: The present invention relates to a well-bore sensor apparatus and method. The apparatus includes a downhole tool carrying at least one sensor plug for deployment into the sidewall of a well-bore. The apparatus may also be used in conjunction with a surface control unit and a communication link for operatively coupling the sensor plug to the surface control unit. The sensor plug is capable of collecting well-bore data, such as pressure or temperature, and communicating the data uphole via a communication link, such as the downhole tool or an antenna. The downhole data may then be analyzed and control commands sent in response thereto. The sensor plug and/or the downhole tool may be made to respond to such control commands. In some embodiments, multiple surface control units for corresponding wells may be networked for decision making and control across multiple well-bores.

    摘要: A technique is provided to control flow in subterranean applications, such as hydrocarbon fluid production applications. The technique utilizes an aggregate formed, at least in part, of particles that swell in the presence of a specific substance or substances. The aggregate is deployed as a slurry or in other forms to desired subterranean locations. Once located, the aggregate allows the flow of hydrocarbon fluids but swells upon contact with the specific substance or substances to limit inflow of undesirable fluids.

    摘要: A gas inflow control system is used in a well. A downhole tool is combined with an automatic valve that is automatically actuatable to a flow position in the presence of a well liquid flowing into the downhole tool. In the presence of gas flow into the valve, the valve automatically transitions toward or to a closed position.
