METHOD FOR ENHANCED OIL RECOVERY USING CYCLIC STEAM STIMULATION AND ELECTROMAGNETIC HEATING

摘要

A method for enhanced oil recovery using cyclic steam stimulation (CSS) and electromagnetic heating (EMH). One or more CSS cycles are conducted on a subsurface hydrocarbon reservoir in order to dilate the reservoir and improve permeability, followed by EMH application for thermal recovery of the hydrocarbon to surface. The alternating process can be repeated as desired while economically viable. The method is particularly applicable to produce heavy hydrocarbons such as bitumen or heavy oil from a heterogeneous reservoir that has low permeability.
