Abstract
Un puits peut croiser une strate minéralisée. Un liquide de fracturation sous forme d'un gaz non participant peut être injecté dans la strate à des débits élevés, pour créer une pression élevée dans le fond de trou, et une impulsion de temps versus pression sur une période de temps. Une deuxième impulsion peut suivre la première impulsion, et une troisième impulsion peut suivre la seconde impulsion, en succession relativement rapide. Il peut y avoir des pauses, ou une période de relâchement relative entre les impulsions.
