ABSTRACT:
A first underground deposit of lignite or coal is heated by magnetic induction to recover hydrocarbon liquids and gases. The carbon remaining is combusted with air and steam to produce a gas which is combusted to generate electrical energy. The electrical energy is transmitted to second underground deposits of oil shale, tar sand or heavy oil, and is used to heat the second deposits in order to recover hydrocarbon liquids and gases.
