Abstract
Implementations of a system, an apparatus, and a method are disclosed herein. In one implementation, a system configured for use in a wellbore drilled through one or more subsurface formations comprises a tubing string including one or more tubulars, a sliding side door (SSD) sleeve configured to move between an open position and a closed position, at least one snap ring, and a pressure-biased tubular, wherein the pressure-biased tubular and the SSD sleeve are coupled via the at least one snap ring.
Claims20
A system configured for use in a wellbore drilled through one or more subsurface formations, the system comprising:
- a tubing string comprising one or more tubulars, wherein an annulus exists between the tubing string and the wellbore;
- a sliding sleeve configured to move between an open position and a closed position;
- a biasing piston configured to move between an open position and a run-in position;
- and
- a snap ring configured to selectively couple the sliding sleeve and the biasing piston, wherein the snap ring is configured to couple the biasing piston in the run-in position to the sliding sleeve, and wherein the biasing piston and the sliding sleeve are configured to decouple from the snap ring when the biasing piston is in the open position.
An apparatus configured for use in a wellbore formed in one or more subsurface formations, the apparatus comprising:
- a sliding sleeve configured to move between an open position and a closed position;
- a biasing piston configured to move between an open position and a run-in position;
- and
- a snap ring configured to selectively couple the sliding sleeve and the biasing piston, wherein the snap ring is configured to couple the biasing piston in the run-in position to the sliding sleeve, and wherein the biasing piston and the sliding sleeve are configured to decouple from the snap ring when the biasing piston is in the open position.
A method comprising:
- conveying a remotely operated valve (ROV) assembly into a wellbore formed in one or more subsurface formations, wherein the ROV assembly includes a sliding sleeve and a biasing piston selectively coupled via a snap ring, and wherein the sliding sleeve is in a closed position when the ROV assembly is conveyed into the wellbore;
- applying a tubing pressure to the biasing piston to move the ROV assembly, wherein the sliding sleeve is moved to an open position after the biasing piston has moved a first axial distance;
- and
- decoupling, via the snap ring, the biasing piston from the sliding sleeve after the biasing piston has moved the first axial distance.
