ABSTRACT:
A method of treating a hydrocarbon producing well involves injecting into the well a combustible mixture including a gaseous phase material. The combustible mixture is ignited to produce a quantity of hot combustion products which flow into a hydrocarbon bearing formation. Because of the relatively rapid travel of these combustion products, some fracturing of the formation occurs adjacent the well bore which increases permeability of the formation. When the formation contains low gravity, high viscosity oil, the hot combustion products also heat the oil thereby lowering its viscosity and also provides some gas which may become intermingled or dissolved in the oil to provide a drive mechanism for moving the oil into the well bore where it can be recovered by conventional pumping devices.
