A liner and a method of setting the liner. The liner includes an outer tubular member, a hydraulic actuator on an outer surface of the outer tubular member for hydraulically setting a packer of the liner, and a hydraulic channel for directing fluid through the outer tubular member and into the hydraulic actuator to set the packer. The hydraulic channel has a first port at an inner surface of the outer tubular member and a second port at the outer surface of the outer tubular member at an axial location of the hydraulic actuator. The first port is at a different axial location of the outer tubular member than the second port. A fluid is pumped through the hydraulic channel into the hydraulic actuator to set the packer.

A downhole tool for applying a force to a component in a borehole penetrating a subsurface formation includes an acoustic transducer configured to receive an acoustic signal. The tool also includes a spring having a spring force, a spring force retention device defining a perimeter having a gap and in mechanical communication with the component where the spring force retention device being configured to retain the spring force, and a gap member configured to be disposed in the gap. The tool further includes a force generator coupled to the gap member and in operable communication with the acoustic receiver and configured to operate in response to receiving the acoustic signal to withdraw the gap member from the gap to cause the spring force retention device to release the spring force thereby applying the spring force to the component.

Remotely-activated liner hanger and running tool

An annular space is made smaller with a hub on an inner member that supports a base ring from which extend bristles that are preferably wire whose proximity is close enough to retain debris from passing through while leaving sufficient fluid paths to allow fluid movement in opposed directions in response to relative axial movement of the components that define the annular space. In one application a running tool for a liner string that has a hanger/packer is contemplated. Movement of the running string after the hanger is set and the liner is released from the string keeps the barrier in the annular space while allowing movement of an initially inserted gel put there on assembly to migrate from the annular space through the debris barrier. The running tool can have a cap on the liner top that eventually is moved away as the running tool is picked up.

A subterranean tool can drop multiple objects to landing locations in a tubular string. The tool can keep at least one ball out of the fluid stream until ready for release. A dart or wiper plug can be kept in the fluid stream with an open bypass until axial mandrel movement allows release of the plug or dart. The tool is rotationally locked at a lower location for run in and then can rotationally lock at an upper location upon release of the dart or ball shifting relative rotation capabilities to different members. Axial movement that releases the dart also aligns a ball with a decreasing depth groove so that relative part rotation can cam the ball against a leaf spring detent and into the mandrel flow path.

A top down cementing tool operates with either mechanical manipulation or hydraulically. Rotation of the liner during cementing is enabled. A first bore is open for circulation during running in of the liner. In the hydraulic version, pressuring up on a dropped ball in the first bore opens cement packer setting ports and aligns crossover ports from the first bore to the annulus below the cementing packer and displaced fluid return ports to the annulus above the cementing packer. Pressuring up on a trailing wiper plug in the first bore opens the second bore so that pressuring on a seated ball in the second bore opens access to unsetting the cementing packer and launching the ball in the second bore for liner hanger setting and release of the running tool. The alternative embodiment gets the same result but with string manipulation for some of the realignments.

A dart or wiper plug can be kept in the fluid stream with an open bypass until axial mandrel movement allows release of the plug or dart. The tool is rotationally locked at a lower location for run in and then can rotationally lock at an upper location upon release of the dart or ball. Axial movement that releases the dart can continue until the ball aligns with a decreasing depth groove so that relative part rotation cams the ball against a leaf spring detent and into the mandrel flow path.

A borehole metal member bonding system includes, a first metal member, a second metal member proximate the first metal member, and a pyrotechnic composition positioned proximate the first metal member and the second metal member configured to bond the first metal member to the second metal member subsequent undergoing an exothermic reaction while within a borehole.
