摘要： Pressure-balanced accumulator apparatus for use in subsea operations is disclosed which comprises a housing and an accumulator within the housing at the first end of the housing. The accumulator has first and second chambers that are hermetically sealed from one another, with a pressurized gas in the first chamber and a pressurized fluid in the second chamber. A third chamber in the housing abuts the accumulator and contains silicon oil fluid. A movable piston is located within the housing proximate the second end of the housing. Ambient pressure is communicated to one end of the piston, and ambient pressure plus the pressure in the second chamber is communicated to the second end of the piston. The cross-sectional areas of the two ends of the piston are selected to optimize the pressure at which the piston begins to expel fluid from the second chamber.

摘要： A packer and service tool assembly for oil or gas well preparation includes a disengageable coupling mechanism which permits the tool to be screwed into and out of the packer and which can be hydraulically disengaged so that the tool can be removed without applying torque to the tool or workstring. A releasable ratchet mechanism is also provided in the packer for trapping the setting loads when the packer is set in the casing. The ratchet mechanism is releasable by pulling up a housing portion which cammingly engages collapsible ratchet fingers thereby disengaging the ratchet finger trapping teeth from a stationary ratchet ring.

摘要： A technique enables protection of subsea wells. The technique employs a subsea test tree designed to ensure control over the well in a variety of situations. The subsea test tree is formed with at least one shut-off valve to protect against unwanted release of fluids from the subsea test tree. The subsea test tree also is coupled with and controlled by a control system having a subsea control module mounted to an interior mandrel.

摘要： An isolation assembly that employs a pack-off device at an annular space between a landing string and a riser. The assembly is configured to ensure sealing off of an annular space below the pack-off device such that potentially hazardous well testing applications may safely proceed early on in completions operations. That is, in advance of any significant rig-level pressure control equipment hook-up, the pack-off device may seal off the annulus from any potential hydrocarbon leaks up the riser toward the rig. Further, where such seal holds back pressures exceeding a predetermined level, a burst element may be incorporated into the wall of the riser to allow for controlled venting therefrom.

摘要： A technique enables a simplified approach for providing subsea hydraulic control. A subsea installation comprises one or more devices that are actuated hydraulically. A simple signal carrier, such as a wireline logging cable, can be routed down to the subsea installation. However, hydraulic fluid for controlling the one or more hydraulic devices in the subsea installation is delivered via an open water umbilical that extends to the subsea installation from a separate workover control system.
