  • Patent number: 10392884
    Abstract: Wall openings in a mandrel of a liner hanger/packer are eliminated and setting is accomplished with pressure against a landed object in a running tool. The wall of the running tool leads to a sealed annular space with a movable seal attached to a setting sleeve and the other end is a packer cup supported by the running tool. The setting sleeve sequentially sets the slips and releases the running tool followed by setting the packer seal. Optionally a dog sub can be used to set with set down weight on the setting sleeve. The set positions are locked in. The slips can be alternatively set with release of a contained spring force. The setting sleeve seal can be sheared out to allow removal of the running tool.

  • Patent number: 10392900
    Abstract: A technique facilitates mechanical operation of components, e.g. valves, without utilizing electronics at the components or control lines routed to the components. An actuation control system is fully mechanical in the sense that it is constructed to mechanically shift to different control positions via pressure input, such as pressure input supplied along a wellbore annulus. The actuation control system utilizes a spool valve coupled with a pilot control circuit which establishes a reference pressure that can be used in shifting the spool valve to different operational positions.
