  • Patent number: 7717185
    Abstract: A combination penetration tool for access to the control system of a subsurface safety valve also has a lockout for the flapper that operates by latching into a nipple profile near its upper end as a series of collet fingers pass through a sleeve that is held in the locked position on the valve housing. One or more dogs on the collet fingers line up with the flapper already pushed open by the advancing collet fingers to push the flapper further back. A second series of dogs get past the sleeve after moving through it. With a jar up force the second series of dogs overcomes a lock on the sleeve and shifts the sleeve to overlap the open flapper and allow the lock ring that moves with the sleeve to latch into the housing. The second series of dogs is sheared off but retained by the tool for removal from the well. The penetrator portion of the tool is a known device that preferably works by jarring up.

  • Patent number: 5584488
    Abstract: A seal is provided for a connector which must be reliably sealed in applications where the connection is made and undone as part of the normal use of the connector. The seal is particularly well suited to on-off tools used in downhole applications. The seal comprises of a nonmetallic insert holding bonded seals, preferably made of rubber. The nonmetallic insert provides support against seal extrusion. It also does not damage the sealing surface if movement or flexing result in contact between the insert and the opposed sealing surface.
