Abstract: A system includes a downhole valve, a pressure gauge mounted on the downhole valve, and a power source for powering the pressure gauge. The pressure gauge is programmed to interpret a pressure command characterized by at least two variables of a pressure signal to open the downhole valve.

Abstract: An isolation valve system includes a well string having an isolation valve including a ball rotatably mounted to a pair of inserts for rotation about a fixed axis, an arm coupled to the ball at a position offset from the fixed axis, and a mandrel connected to an actuation end of the arm, the mandrel and the actuation end of the arm being disposed uphole of the ball. Via the actuation end of the arm, the mandrel forces rotation of the ball from a closed position to an open position by moving in a linear direction away from the ball, which allows flow of fluid along a through hole of the ball.

Abstract: A well completion has an inner completion with a control valve surrounded by spaced seals that is positioned in an outer completion, such as a sand control completion. A control line extends from the valve through one of the seals. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
