Internally catalyzed well consolidation method

Patent ·
OSTI ID:6555548
A method is described for permeably consolidating sands in a well wherein a consolidating fluid consisting of a hydrocarbon carrier, an acid catalyzed resin or resin-forming material, sand and an acid-producing material is introduced into an incompetent earth formation. Acid is produced by the acid-producing material, causing the resin to harden. Specific acid-producing materials are disclosed as catalysts which are composed of surfactants which release acid upon heating, and ammonium salts which hydrolyze to produce an acid. (5 claims)
