Abstract
A method of producing subterranean fractures in geologic formations having a significant amount of water present (a wet well) and/or at deep locations (1.5-2 miles or more) for the extraction of hydrocarbons therefrom includes flowing an explosive hydrophobic emulsion mixture to protect the air and fuel mixture subsequently flowed into a well hole. The build-up of pressure using a multiple plate restriction orifice assembly eventually causes auto-ignition of the air and fuel mixture which fractures the formation for recovery of the hyrdrocarbons.
