Abstract
A setting tool for actuating a downhole plug in a wellbore includes a housing including a central passage, a piston slidably disposed in the housing and including a central passage, and wherein the piston includes a first position in the housing and a second position the housing spaced from the first position in a first axial direction, and an atmospheric chamber filled with compressible fluid formed radially between the piston and the housing, and wherein the atmospheric chamber is sealed from an environment surrounding the setting tool when the piston is in the first position, wherein, in response to a pressurization of the central passage of the piston, the setting tool is configured to displace the piston from the first position to the second position and compress the compressible fluid within the atmospheric chamber.
