Abstract: A seal assembly (60) for controlling the flow of fluids in an annulus (68) between a continuous tubular (62) and a cased wellbore (64) is disclosed. The seal assembly (60) includes anchor slips (72) and a seal element (78). The seal assembly (60) is actuated by communicating hydraulic fluid to a setting assembly (82) via an operating fluid conduit integral with the tubular (62). Upon actuation, the setting assembly (82) axially shifts a pair of slip ramps (74, 76) which radially expands the anchor slips (72) into gripping engagement with the wellbore (64) and radially expands the seal element (78) into sealing engagement with the wellbore (64).

Abstract: A well tool lock mandrel and running and pulling tools for installing and retrieving the lock mandrel. The lock mandrel is used for supporting a well tool such as a subsurface safety valve at a landing nipple in a well tubing string. The lock mandrel includes a tubular body, locking dogs supported in the body, an expander sleeve for operating the locking dogs, and a latch for releasably locking the expander sleeve when the locking dogs are locked outwardly. The running tool includes a head assembly for connection with a wireline tool string, an upper retainer key assembly for connection with the head of the lock mandrel, and a lower locking lug assembly for engagement with the expander sleeve of the lock mandrel for operating the sleeve. The running tool also includes a spring biased insertion sleeve for operating the lower locking lug assembly permitting the running tool to be installed in the lock mandrel when the locking dogs of the lock mandrel are at inward positions.

Abstract: Well tools for running and setting a well safety valve including a lock mandrel for releasably locking the valve at a no-go landing nipple in a well bore and a running tool for running and setting the lock mandrel. The lock mandrel includes a body provided with a no-go ring, locking dogs on the body, and an expander sleeve movable upwardly in the body for expanding and locking the dogs. The running tool includes a tubular core having an end engageable with an operating tube of the safety valve, an upper latch assembly for engaging the lock mandrel housing to couple the running tool with the lock mandrel, a lower latch assembly for operating the expander sleeve of the lock mandrel to expand the mandrel locking dogs, and a head for connecting the running tool in a wireline tool string. The running tool has locking features which apply a force from a spring of the safety valve to the upper latch assembly to lock the running tool with the lock mandrel.
