Abstract
A downhole flow control system utilizes a tubing pressure operated valve to selectively open and close fluid flow across the system. The tubing pressure operated valve includes a piston responsive to tubing pressure, and a valve element responsive to piston movement. The valve element can be moved rotationally, longitudinally, or both, in response to the piston movement. The valve is movable between a closed and at least one open position. The piston and valve elements can be releasably attachable, such as by a one-way ratchet. The valve element can be a rotating valve operable by a J-slot mechanism to rotate to multiple positions in response to movement of the piston element.
