Perforating

83 result(s) found.

perforating  A critical step in production often involves opening wellbore tubulars to the reservoir. This is typically achieved through the use of specialized explosive shaped charges that create holes in the casing and liner positioned adjacent to the producing formation. The perforation tunnels created by these charges can penetrate the formation, often beyond the near-wellbore zone damaged during drilling or completion.
