StimGun Assembly™

 

  • The StimGun Assembly™  is a field proven method of perforating and stimulating in one run.
  • Thousands of successful stimulations since its introduction in 1996
  • Assembly consists of four components - perforating gun, sleeve of propellant, retaining rings, and finned subs.

Propellant based well stimulation

StimGun - your first choice!


Combining perforating with stimulation  - IN ONE RUN - has multiple advantages - from lower costs to a more efficient stimulation.

Applications

Used to fracture the reservoir rock in the near wellbore area.  This fracturing process is utilized to enhance additional stimulations or to ensure conductivity to the reservoir.  Example applications
  • Single run perforating and stimulation
  • Pre-hydraulic fracturing breakdown
  • TCP under and over balanced perforating and stimulation
  • Stimulation of near gas /oil / water contact reservoirs
  • Injector well remediation
  • Perforating, stimulating, and acidizing
  • many more
