Abstract
A method for stimulating the production of hydrocarbonaceous fluid from a subterranean geologic formation in the earth during microwave heating of same wherein a portion of high electrical conductivity non-hydrocarbonaceous fluid present in the formation near the wellbore in which microwave heating is taking place is displaced away from the wellbore to substantially reduce the overall electrical conductivity of the formation and its contained fluids in a finite volume around the wellbore thereby increasing the effectiveness of the microwave heating in such finite volume and stimulating the movement of desired hydrocarbonaceous fluid in such finite volume for recovery purposes.
