Abstract

Safety valves and methods of operating the same. An example safety valve includes a first piston disposed within a safety valve body. The first piston forms a first seal with the interior of the safety valve body. The first piston, the interior of the safety valve body, and the first seal define two chambers within the safety valve separated by the first seal. The first chamber is a control line pressure chamber disposed uphole of the first seal, and the second chamber is a fluid compression chamber disposed downhole of the first seal. The control line pressure chamber is pressurized to translate the first piston downhole in an axial direction. A second seal is formed with an annulus outside of and adjacent to the safety valve. A biasing mechanism translates the second piston uphole in the axial direction. A fluid volume chamber is fluidically connected to the fluid compression chamber.
