摘要： A safety valve system includes a safety valve having an actuator and a line connected to the actuator. The safety valve is operable by opening the line in the well, with the line being free of any connection to a surface control system. Another safety valve system includes multiple safety valves. An actuator of each safety valve is connected to an actuator of another safety valve via a line. A biasing force in each of the actuators is operative to close the respective one of the safety valves in response to opening of the line. The biasing force is produced at least in part by hydrostatic pressure in a well.

摘要： A hydraulic control and actuation system for downhole tools. In a described embodiment, a hydraulic control and actuation system includes an internal chamber serving as a low pressure region and a well annulus serving as an energy source. A valve assembly provides selective fluid communication between alternating opposite sides of a piston and each of the energy source and low pressure region. Displacement of the piston operates a well tool. Operation of the valve assembly is controlled via telemetry between a remote location and an electronic circuit of the system.

摘要： A fluid sampler operable for taking at least one fluid sample in a subterranean well and associated methods. A fluid sampling method includes the steps of disposing a fluid sampler at a first target location in the well, receiving the fluid sample into at least a first sample chamber of the fluid sampler, pressurizing the fluid sample in the first sample chamber using a pressure source of the fluid sampler, retrieving the fluid sampler to a surface location, isolating the fluid sample in the first sample chamber from the pressure source of the fluid sampler and supercharging the fluid sample in the first sample chamber using a pressure source on the surface.

摘要： A rotary control valve and associated actuator control system. An actuator control system comprises a rotary control valve including a generally planar face seal, and an actuator operatively connected to the rotary control valve. Another actuator control system comprises a control valve including multiple faces having multiple ports formed therein. Fluid communication is selectively permitted and prevented between the ports in response to relative displacement between the faces. A differential area is configured to apply a biasing force which maintains sealing engagement between the faces, and which increases in response to an increase in pressure applied to the control valve.
