摘要： A retrievable well lock for use within a subterranean member is used in cooperation with a tool for setting the lock. The lock will include an actuation assembly which is operable in response to longitudinal movement between portions of the lock. The setting tool will preferably include a power source within a housing assembly which can be selectively coupled to or decoupled from the lock assembly. The power source is associated with the setting tool through an activation assembly which will cause movement of a movable mandrel within the setting tool facilitating the selective actuation of the lock.

摘要： The present invention provides a packer releasing tool for releasing a packer from a wellbore where the packer is coupled to a tubing string and has a releasing profile with a packer uphole shoulder and a packer downhole shoulder. The packer releasing tool preferably comprises a toplock assembly removably coupled to a downlock assembly. It also includes a toplock key that is movably coupled to the toplock assembly and that has a toplock key profile engageable against the packer releasing profile. Also present is a downlock lug that is movably coupled to the downlock assembly and that has a downlock lug profile engageable against the packer releasing profile. In one embodiment, the packer releasing tool has an outer diameter that is less than the inner diameter of the tubing string. This unique configuration allows the packer to be pulled without the need of first removing the production string.

摘要： A communication tool (100) includes a housing (102) having recesses (110) and a set of axial locating elements (112) radially extendable through the recesses (110) and engagably positionable within a profile of a tubing retrievable safety valve (50). An anti rotation device (140) is radially outwardly extendable relative to the housing (112). The anti rotation device (140) operably engages the tubing retrievable safety valve (50) to substantially prevent relative rotation between at least a portion of the communication tool (100) and the tubing retrievable safety valve (50). A cutting tool (148) is radially outwardly extendable relative to the housing (102). The cutting tool (148) is operable to create a fluid passageway (150) between a non annular hydraulic chamber (60) and an interior the tubing retrievable safety valve (50).

摘要： Method and apparatus for pressurizing the top of the valve member of a subsurface safety to equalized pressure thereacross and assist in opening the valve. The apparatus includes a chamber filled with fluid under pressure which is admitted in to the space between the apparatus and a valve when landed in the valve to pressurized the valve. A spring loaded prong on the apparatus urges the valve member of the safety valve to open position. A latch is included which will bypass a top landing nipple and land in a second landing nipple. The subsurface safety valve is provided with means for filling its spring chamber with liquid with the valve closed. When the safety valve is open the spring chamber is isolated to protect the chamber from flow of fluids and solids.

摘要： A well tubing hanger for suspending a pressure bomb, and/or temperature recording device or other equipment, in the tubing, from a selected tubing nipple, through a test period. It is a bomb hanger such that when the suspended equipment is in use for test surveys, the wire line used to run the tools is not left in the well, thereby achieving considerable savings, particularly when a plurality of wells in a field are surveyed. Hanger locking lugs are shifted radially outwardly into a position-selected matching nipple recess when brought into operational alignment therewith, after lug latch members have been released by unlocking upward movement engagement with a tubing nipple shoulder. A lug-locking sleeve is movable into lug locking position with the sleeve lockable by a ball recess lock interference fit. A resiliently-displaceable plunger structure permits a recess relief unlock for the balls, from the ball recess lock interference fit, and thereby permits unlock release movement of the tubular sleeve with the tool fishing neck for unlocking the locking lugs from the extended state.
