20090159290 | Controller for a Hydraulically Operated Downhole Tool - A hydraulic control system can be used on a downhole choke and has the feature of moving a travel stop for a sliding sleeve using discrete j-slot mechanisms for selectively moving the stop in either one of two opposed directions. The valve can be incrementally opened further with pressure cycling on an opening chamber. The valve can be immediately put to the closed position with pressure on a closing chamber. After closing, the valve can assume its former open position or other selected less open positions by reconfiguring the travel stop while the valve stays in the closed position In order to achieve a higher open percent after closing, one or more pressure cycles must be applied to the open chamber after the valve is reopened to the position it was in before it was closed. | 06-25-2009 |
20120132414 | Automatic Bypass for ESP Pump Suction Deployed in a PBR in Tubing - A subterranean pump is delivered on coiled tubing with power and control cables running inside. The pump suction has a tubular inlet that seals in a polished bore in the surrounding tubular. A diverter opens a lateral port and closes entry to the pump suction when the pump is not running and the formation pressure is high enough to bring production to the surface. This configuration prevents the pump from turning while the formation pressure allows production to the surface. If the pump is started it reduces pressure ahead of a movable plug to draw it toward the pump against a spring bias. The lateral ports close and an inline flow path opens to allow the pump to draw through the diverter and discharge into the annular space around the coiled tubing on the way to the surface. | 05-31-2012 |

The system is configured such that both the first valve and the second valve are open when the member is in a first position, the first valve is closed and the second valve is open when the member in a second position, the first valve is open and the second valve is closed when the member is in a third position, and the first valve and the second valve are both closed when the member is in a fourth position. The first valve and the second valve are closable in response to retrieval of an upper completion. | 10-11-2012 |
20130068472 | Hydraulic Three Position Stroker Tool - A stroker tool operates a subterranean tool between three operating positions. The stroker tool includes an outer housing defining a piston chamber within. A piston assembly having first and second piston members is moveable within the piston chamber between a first position, a second position, and a third position. A shifting member is operably connected with the piston assembly and is moved to an uppermost axial position when the piston assembly is in the first position, an intermediate axial position when the piston assembly is in the second position, and a lowermost axial position when the piston assembly is in the third position. | 03-21-2013 |
20130153203 | Subterranean Tool with Shock Absorbing Shear Release - A subterranean tool can be actuated with one or more control lines for a hydraulic release. It can further be actuated with a shear release after a lockout feature for the shear release is defeated. The shear release features a lock that limits relative movement so that a shear member can be defeated but without a release. A dog limits relative movement in a wider groove where dog movement in the groove allows a shock absorbing feature to act to cushion the release as the shear member breaks. The relative movement is reversed to let a retaining ring drop out of the way into a groove that comes into alignment with it. The relative movement is reversed again to pull a sleeve out from under gripping collets that have previously failed to release and the tool releases from that point on the same way as the control line actuated release. | 06-20-2013 |

It can further be actuated with a shear release after a lockout feature for the shear release is defeated. The shear release features a lock that limits relative movement so that a shear member can be defeated but without a release. A dog limits relative movement in a wider groove where dog movement in the groove allows a shock absorbing feature to act to cushion the release as the shear member breaks. The relative movement is reversed to let a retaining ring drop out of the way into a groove that comes into alignment with it.

In a described embodiment, the setting module also includes a frangible rupture member that closes off the setting chamber from annulus pressure. A regulator governs the transfer of fluid pressure from the collapsible chamber to the setting chamber. | 11-07-2013 |
