This is an animation of a well stimulation performed with the use of a GasGun propellant stimulation tool. In this example, the GasGun tool is conveyed into the well on wireline, but it can also be run on conventional tubing or coil tubing.


This is a video of a GasGun surface test conducted by our Croatian distributor. A 0.5 meter GasGun was ignited inside perforated pipe. The perforated pipe was necessary to confine the propellant and allow for a proper burn. The first explosion is the blasting cap and detonating cord. The following rush of gas coming out of the holes is the propellant burn. The entire event takes ~2 seconds, but in a well the burn takes only ~20 milliseconds due to higher confining pressures. The rate of gas coming out of the holes continually increases until the burn is complete. This is due to the progressive burning properties of our propellant.

This video is from a downhole camera used before and after a GasGun stimulation. The stimulation was conducted in a shallow Berea sandstone well located in Ashland County, Ohio. The well was an open hole completion which makes it possible to observe the multiple fractures created by the GasGun.


This is a GasGun propellant stimulation being conducted in the Big George Coal formation of the Powder River Basin. Nine 10-foot GasGun tools were shot across 100 feet of perforations in 5.5 inch casing. This entire stimulation was conducted in about 3 hours.


This is a presentation given by Richard A. Schmidt, Ph.D., inventor of the GasGun propellant stimulation tool, to Chesapeake Energy during a lunch and learn. Dr. Schmidt discusses how the GasGun compares to other oil and gas well stimulation methods, the research behind the development of the GasGun tool, how it is fielded, and the benefits associated with using this particular technology.


This is a video of the first multi-stage GasGun propellant stimulation conducted in a horizontal well. A total of 8 stages were stimulated covering 859 meters of pay. The GasGun propellant tools were conveyed into the well via drill pipe and initiated with a ball-activated differential-pressure firing head. All 8 stages were stimulated successfully with no misruns.
