Geothermal energy recovery from abandoned oil wells

摘要

A method and apparatus for recovering geothermal heat from abandoned sub sea oil wells and converting it to electricity which is then transmitted via cable to an onshore station for distribution to the electric grid. To accomplish this we insert a unique heat transfer recovery pipe into the well bore of these dormant oil wells and transfer the heat from the oil/brine and rocks surrounding these wells and the oil and brine in the lower portion of these wells to a continuous stream of a fluid such as water which is pumped through the heat transfer pipe to a vessel located on the ocean floor or on a water surface platform. This hot fluid will be continuously pumped to a heat exchanger to exchange heat to another heat transfer gas which will drive a turbine. The turbine will drive a generator to produce electricity.
