StimGun^®

The StimGun^® family of propellant-based products provides the industry with fully integrated, technology-based tools to dynamically clean and stimulate the near wellbore. These stimulations are cost effective as a primary stimulation and in conjunction with other stimulation technologies such as hydraulic fracturing.

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 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.
