Abstract: An actuator assembly of a downhole tool may include a high pressure chamber and a low pressure chamber. A pressure applied from the surface to the tool may enter both chambers. The low pressure chamber may include an inlet that restricts the flow of pressure and prevents the pressure within the low pressure chamber from increasing quickly. The high pressure chamber may also include an inlet that restricts the flow of pressure to prevent the pressure within the high pressure chamber from increasing quickly. The inlet of the high pressure chamber may also include a check valve that prevents pressure from bleeding off from the high pressure chamber through the check valve. The pressure within the high pressure chamber may actuate a piston to actuate the tool in response to the pressure applied from the surface falling within a predetermined pressure and time range.

A sensor piston having first and second positions relative to the housing is slidably disposed within the housing, the second open port fluidly uncoupled from the second close port through the bypass channel when the sensor piston is in the first position, second open port fluidly coupled to the second close port through the bypass channel when the piston is in the second position for reducing fluid resistance to mechanical operation of the slave valve in a mechanical override intervention operation.

Abstract: This disclosure provides a multi-ball valve assembly that lessens the pressure applied from either uphole or downhole directions by directing a portion of the pressure into a sealed fluid chamber area between two balls that are operatively coupled together by one or more control arms. The multi-ball valve assembly may be a floating design where the balls move axially with respect to each other or fixed designs that use either pressure relief valves or biased travel piston valves to divert a portion of the pressure into the fluid chamber area, thereby lessening the distortion of the face of the ball valve against which fluid pressure is being applied.

Abstract: A method, a device and a system for activating a running/setting tool are provided. The method includes: 1) detecting a wellbore condition at the running tool, 2) based on a signal from surface equipment received at the running tool, initiating an isolation of pressure below the running tool from pressure above the running tool, and 3) if the signal is not received at the running tool, initiating the isolation of pressure below the running tool from the above at a predefined time based on the wellbore condition.

The actuating apparatus is adapted to be fluidly coupled to the downhole valve.

Abstract: A downhole valve assembly operable to control production fluid flow around an obstruction in a production tubing string. The obstruction may be caused by another valve or valve assembly located in the production tubing string, where the valve is closed and blocks flow through the production tubing. The downhole valve assembly comprises a tubular body that includes an axial passage extending through the body and one or more ports extending substantially radially through the body. The downhole valve assembly also includes one or more actuating members operable to move relative to the body. Movement of the actuating members selectively opens the ports such that a fluid flow path through the ports is defined between an annulus region outside of the valve assembly and the axial passage such that the blockage can be bypassed.
