Abstract: 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.

Abstract: 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.
