20080202761 | Method of functioning and / or monitoring temporarily installed equipment through a Tubing Hanger. - The invention covers the method of supplying services to a device such as a Subsea Intervention Tree and Retainer Valve using conduits routed through a tubing Hanger. The method of this invention provides control of equipment sitting within the BOP stack and/or marine riser using control systems located external to the Marine riser. This removes the need for a costly umbilical/conduit to be run alongside the casing or tubing string within the marine riser, thereby reducing cost and risk of damage during deployment of the string. Running time will be significantly reduced saving valuable rig time. Also, in deeper waters complex Electro/Hydraulic or MUX control systems traditionally run within the Marine riser and/or the BOP stack as a part of the Landing string can be replaced by a local control system located outside the Marine riser on or around the Production Tree. | 08-28-2008 |

20140262312 | SLIDING SLEEVE BYPASS VALVE FOR WELL TREATMENT - A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation. | 09-18-2014 |
