StimGun™

StimGun™ overcomes formation damage created during perforation. The StimGun™ assembly used in the Mara-Stim process employs a cylindrical sleeve of gas-generating propellant that is simply slid in place over the outside of conventional perforating guns. It can be run on wireline or in a tubing conveyed configuration. The propellant sleeve is ignited by the perforating charge and as the propellant sleeve burns, energetic gases are released sending a high pressure shock waves through the casing and into the formation. This method of perforating does not crush the formation rock, therefore reducing formation damage.
