Patent Number Title Of Patent Date Issued
7487827 Propellant cartridge with restrictor plugs for fracturing wells February 10, 2009
An apparatus for fracturing a well has a propellant charge held by a carrier, and upper and lower restrictor plugs secured to the carrier above and below the propellant charge, respectively. The restrictor plugs allow a restricted flow of combustion gases generated by the propellant
7409911 Propellant for fracturing wells August 12, 2008
An apparatus for fracturing wells employs a propellant charge and an ignition cord wrapped around the outer surface of the propellant charge to rapidly ignite the outer surface of the propellant charge.
7073589 System for fracturing wells using supplemental longer-burning propellants July 11, 2006
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
