101mm GasGun® System

101mm OD/70mm ID High Strength Steel Carrier

The GasGun is a solid-propellant well-stimulation device based on proprietary ballistic technology from the U.S. military. It incorporates the most advanced design on the market with the use of progressively burning propellants that have been proven by independent research to be many times more effective in creating fractures and increasing formation permeability.


  • Most powerful GasGun tool available.
  • Creates multiple radial fractures into the formation up to 15 meters (50 feet) from the wellbore.
  • Designed for 7” casing and larger or 6” open hole and larger.
  • Generates nearly twice the energy of the 3.375”/ 86mm OD system resulting in longer and wider fractures.
  • Wireline and tubing-conveyed systems available for both vertical and horizontal wells.
  • Reusable high strength steel carrier and subs.
  • Arming procedures comply with API RP-67.
  • Patented design.


  • Minimal vertical fracture growth avoids problems often associated with hydraulic fracturing.
  • Removes skin and cleans up the wellbore damaged by perforators, drilling fines, cement, paraffin, mud cake, etc.
  • Improves effectiveness of acidizing by fracturing first with the GasGun.
  • Enhances production in naturally fractured reservoirs by intersecting more fractures.
  • Prepares well for hydraulic fracturing by breaking down formation first.
  • Reduces injection pressure and improves flow rates in injection and waste disposal wells.
