Limited penetration perforating methods for oilfield applications

摘要

A method for completing an unconventional subterranean formation include the steps of positioning a perforating tool in a section of the deviated wellbore that intersects the unconventional formation, forming at least one opening in a production structure without substantially penetrating into a surrounding formation by firing the perforating tool, and fracturing the formation by pumping a fracturing fluid through the at least one opening. The perforating tool may include shaped charges that have a charge case, a liner disposed in the charge case, and an explosive material filling an interior of the charge case.
