Abstract
A method for separating oil from geological formations by application of an aqueous oxidant. The oxidant breaks the interfacial attraction between the oil phase and the geological formation and also produces ketone moieties which assist in separating the oil phase from the mineral phase and also dissolve into the oil phase, thereby decreasing the viscosity. The method is especially useful in recovering heavy oil from geological formations wherein oil has been previously extracted to exhaustion by prior art methods.
