Gilman A Hill, Richard S Passamaneck, Kenell J Touryan: Well treating method for stimulating recovery of fluids. Mt Moriah Trust, Hubbard Thurman Turner & Tucker, January 6, 1987: US04633951 (49 worldwide citation)

Subterranean oil and gas producing formations are fractured by providing one or more combustion gas generating units using rocket fuel type propellants disposed in a well casing at preselected depths. The well casing is filled with a compressible hydraulic fracturing fluid comprising a mixture of li ...

Richard S Passamaneck: Method of fracturing wells using propellants. University of Colorado Foundation, Dorr Carson Sloan & Peterson, March 22, 1994: US05295545 (37 worldwide citation)

A propellant is ignited within a well to rapidly produce combustion gases to generate pressure exceeding the fracture extension pressure of the surrounding formation. Combustion gases are generated at a rate greater than can be absorbed into any single fracture, thereby causing propagation of multip ...

A system for fracturing wells uses a primary propellant charge to initially produce pressures within the well in excess of the maximum fracture extension pressure of the surrounding formation, but below that which would cause damage to the well. A supplemental propellant charge burns for a substanti ...
