Abstract
The present invention provides a method of consolidating an incompetent subterrnean formation. An acid curable resin consolidating fluid is positioned within casing in a wellbore in the vicinity of perforations through the casing. A gas generating charge positioned within the casing then is ignited to generate gas pressure which rapidly forces the consolidating fluid through the perforations and into the subterranean formation while substantially simultaneously catalyzing the resin composition. The consolidating fluid is caused to rapidly harden to consolidate the formation in the vicinity of the perforation without any significant permeability loss.
