  • Firing mechanism for a perforating gun or other downhole tool
    Patent number: 10822931
    Abstract: A firing assembly for a wellbore perforating gun or other downhole tool includes: one or more casings connected together to form a firing head containment body, the firing head containment body is in fluid communication with a firing assembly that includes a click pressure firing module that allows the wellbore to be pressurized to high pressures required for pressure testing the well casing one or more times without firing the gun or actuating a certain downhole tool, and after a predetermined number of pressure increase events, allows the subsequent high pressure activation to reach the firing pin or actuation device and fire the gun or activate the tool without further activity from the surface other than applying the pressure.
