Abstract:
1. A hydraulic connector to provide a fluidic connection between a fluid supply and a downhole tubular, the connector comprising: a body; an engagement assembly comprising an extendable portion selectively extendable from the body, the engagement assembly being configured to extend and retract a seal assembly disposed at a distal end of the extendable portion into and from a proximal end of the downhole tubular; and a valve assembly operable between an open position and a closed position, the valve assembly being configured to: allow a fluid to communicate between the fluid supply and the downhole tubular through the seal assembly when in the open position; and prevent fluid communication between the fluid supply and the downhole tubular when in the closed position, wherein the extendable portion comprises a first abutment surface disposed to limit the extension of the engagement assembly by contact of the first abutment surface with a corresponding abutment surface of the body, wherein the engagement assembly comprises a piston disposed about the extendable portion and divides a cylinder defined by the body portion into a first chamber and a second chamber, and wherein the piston comprises a third chamber and one or more passages, the one or more passages fluidicly connecting the third chamber to the first chamber.
