OSTI ID:5693328
A well packer is described which is adapted to be set in a conduit disposed in a well bore having initially retracted packing seal means and initially retracted slip means which are set by opposing acting hydraulically actuated pistons. A single one-way clutch is connected between the pistons allowing simultaneous movement of the pistons for setting and holding the packer centrally in the conduit. A releasable sub includes an abutment member initially positioned against the top of the packing seal means with a housing telescopically surrounding and initially holding the abutment in position. An outer member is releasably connected to the housing and to a packer expander sleeve and various coacting shoulders are provided between the components whereby vertical movement upwardly of the packer housing will release the set packer.
