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： A technique enables protection of subsea wells. The technique employs a subsea test tree and associated control system to ensure control over the well in a variety of situations. The subsea test tree may be formed with an upper portion releasably coupled to a lower portion. The upper portion employs at least one upper shut-off valve, and the lower portion employs at least one lower shut-off valve to protect against unwanted release of fluids from either above or below the subsea test tree. The subsea test tree also is coupled with the control system in a manner which allows control to be exercised over the at least one upper shut-often valve and the at least one lower shut-off valve.

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 tool that is usable with a well includes a valve element, a mechanical operator, a pressure chamber and a regulator. The valve element has a first state and a second state. The mechanical operator responds to a predetermined signature in an annulus pressure relative to a baseline level of the annulus pressure to transition the valve element from the first state to the second state. The pressure chamber exerts a chamber pressure to bias the mechanical operator to transition from the second state to the first state. The baseline level is capable of varying over time, and the regulator regulates the chamber pressure based on the baseline level.
