Abstract: A packer system includes a retainer positionable adjacent to a packing element and coupleable to a cylinder of a downhole tool in a wellbore. The retainer is moveable in a first direction along a mandrel of the downhole tool to compress the packing element to a compressed state and generate a seal in the wellbore or to set a slip in response to an applied pressure. The packer system includes a piston moveable in a second direction along the mandrel and configured to compress a spring in response to the applied pressure. The packer system includes an interfacing element configured to couple the cylinder to the piston subsequent to the cylinder moving a predefined amount. The packer system includes a ratchet mechanism configured to prevent movement of the cylinder in the second direction.

Abstract: Systems and methods of the present disclosure relate to isolating a setting chamber of an actuating assembly from tubing pressure. The actuating assembly comprises a cylinder; a mandrel disposed within the cylinder, the cylinder operable to move along the mandrel; a piston disposed between the cylinder and the mandrel, the piston operable to move along the mandrel in a direction opposite to that of the cylinder; a chamber disposed adjacent the piston, wherein the mandrel includes a port operable to allow fluid to pass into the chamber from the mandrel; and a spring disposed adjacent to the piston, the spring operable to expand, upon release of pressure from the chamber, to move the piston to seal the port and isolate the cylinder from pressure within the mandrel.
