Abstract
A method of heating an oil shale formation to produce shale oil includes radiating RF energy into the oil shale formation for a predetermined first time interval from a first borehole which penetrates said oil shale formation. Shale oil is produced when available during said first time interval from a second borehole penetrating said oil shale formation which is a predetermined distance from the first borehole. During a predetermined second time interval, RF energy is again radiated into the oil shale formation from the second borehole while shale oil is produced from the first borehole during the second time interval.
