摘要： A bi-directional valve system for an aquifer thermal energy storage system includes a hydraulic control valve fluidly connected to the aquifer pump and pipeline. A control pump is selectively actuated to hydraulically open and close fluid outlets of the hydraulic control valve. When the fluid outlets are closed, a full flow of water can be pumped from the aquifer, or pressure in the pipeline of the system maintained or increased. However, when the fluid pressure needs to be reduced or water reintroduced into the aquifer, the fluid outlets of the hydraulic control valve are selectively opened.

摘要： A control system (10) for an annulus balanced subsurface safety valve (12). A system for operating a safety valve in a well includes a piston (38) of the safety valve being responsive to displace due to a pressure differential between chambers exposed to the piston; and a valve controller (24) which alternately exposes at least one of the chambers to pressure in an annulus surrounding the safety valve, and to pressure greater than that in the annulus. A method of operating a safety valve in a well includes the steps of: opening the safety valve by biasing a piston of the safety valve to displace in response to a pressure differential between a chamber exposed to pressure greater than well pressure, and another chamber exposed to well pressure; and closing the safety valve by exposing both of the chambers to the well pressure.

摘要： A control system for a downhole tool, such as a subsurface safety valve, features an operating piston that is insensitive to tubing pressure in the valve. The hydrostatic forces from the single control line from the surface are significantly reduced with a branch line to a piston bottom that is slightly smaller than the piston top. A variable volume between piston seals is connected to a low pressure compressible fluid reservoir to permit piston movement. The piston can be modular to facilitate assembly or bore offsets in the valve body. Failsafe closure upon seal failures is contemplated.

摘要： A valve device and associated methods of selectively communicating between an interior and an exterior of a tubular string. A valve device includes an openable and closable flow path for selectively permitting and preventing flow between an interior and exterior of the valve device, and a lock assembly which prevents the flow path from being opened greater than a predetermined number of times. A method of testing at least one annular seal in an annulus formed between a tubular string and a wellbore wall includes the steps of : sealingly engaging the annular seal to thereby prevent flow through the annulus across the annular seal; and applying a pressure differential across the annular seal to thereby test the annular seal, the pressure differential being applied via a valve device interconnected in the tubular string.

摘要： For injecting e.g water into ground formation around a borehole, and for superimposing pulses onto the outflow of the injected water, it is important that the puses have a rapid rise-time. A piston is connected to a pulse-valve of the tool. A bias spring urges the piston towards its closed position. The piston is urged towards the open position by a differential PDAF between the supplied accumulator-pressure and the in-ground formation-pressure. When the pulse-valve is open, the PDAF is falling, until the force of the spring closes the pulse-valve. Then the PDAF rises, but now the PDAF acts over only a small area of the piston. When the PDAF is high enough to ease the pulse-valve open, suddenly the whole area of the piston is exposed to the PDAF, whereby the pulse-valve opens violently.

摘要： well tools are provided which although pressure responsive, may be maintained by a hydraulic lockout in a nonresponsive condition until a threshold actuation step is performed. This lockout may be achieved by a hydraulic mechanism (130) which controls the rate at which pressure is transmitted to a fluid spring during periods of increased pressure at the pressure source. When the tool is desired to be responsive to pressure cycles, a valve may be opened by establishing a differential between the pressure in the fluid spring and the pressure source. Communication of pressure in the fluid spring to a movable mandrel will then allow operation of the well tool in response to pressure cycles at the pressure source in accordance with the established design of the well tool.
