Abstract
A method of fracturing a subterranean formation penetrated by a wellbore utilizing high pressure gas. The method is accomplished by casing the well with high strength casing over a selected zone, installing a bridge plug, tubing conveyed perforating gun and packer over a selected zone and filling the casing between the packer and plug with high pressure gas. The gas is present in an amount sufficient to have a pressure of at least about 1.5 times the breakdown pressure of the formation. Upon perforation of the casing the formation is rapidly contacted with the high pressure gas which causes fractures to form in the formation.
