Abstract
A sealing mechanism is provided. In one embodiment, a system includes a connector configured to couple one or more flow-control valves to equipment installed at a well and an isolation sleeve configured to be retained by the connector. The isolation sleeve may include a seal and a hydraulically actuated piston disposed adjacent one another about a body of the isolation sleeve such that actuation of the piston engages the seal. Additional systems, devices, and methods are also disclosed.
Claims19
A system comprising:
- a connector configured to couple one or more flow-control valves to equipment installed at a well;
- and
- an isolation sleeve configured to be retained by the connector, the isolation sleeve including a body, a seal disposed about the body, and a hydraulically actuated piston disposed about the body adjacent to the seal, wherein the hydraulically actuated piston is positioned to engage the seal and to drive the seal along the body in response to actuation.
A system comprising:
- an isolation sleeve including a body, a seal disposed about the body, and a piston disposed about the body that divides a recess in the body into first and second regions, the body including an internal passageway connected to the first region to enable fluid to be routed into the first region via the internal passageway to actuate the piston and energize the seal by driving the seal along the body.
A method comprising:
- aligning a connector of a well capping system with equipment installed at a well, the connector including an isolation sleeve;
- moving the isolation sleeve into a bore of the equipment installed at the well;
- and
- applying hydraulic pressure to a side of a piston of the isolation sleeve to actuate the piston and engage a seal to cause the seal to be driven over a shoulder of the isolation sleeve to energize the seal against the bore of the equipment installed at the well.
