ABSTRACT:
A method for enhanced oil recovery from a subsurface earth formation is disclosed. At least one essentially upward deviated hole from a vertical shaft in the formation is formed. An outer loop borehole is formed in proximity with the deviated hole. A heating fluid is injected from the surface to the outer loop borehole to heat the formation in proximity with the upward deviated hole to facilitate drainage of oil and the like.
