Abstract:
Systems and methods for producing energy from a geothermal formation. A heat exchanger can be disposed within a well to absorb heat from a geothermal formation. The heat exchanger can be supported within the well using a high thermal conductivity material. The heat exchanger is connected to an organic Rankine cycle engine including a secondary heat exchanger and a turbine. The primary and secondary heat transfer fluids are chosen to maximize efficiency of the organic Rankine cycle.

Claim (Index 30):
A heat exchanger for use in a geothermal application comprising:\n a casing disposed within a well, having an anti-scaling and/or anti-corrosion layer thereon configured to contain a heat transfer fluid, the casing forming a shell to hold a heat transfer fluid; a plurality of support collars disposed within the well, the plurality of support collars supporting the casing within the well, the plurality of support collars disposed at a generally upward angle from an inner surface of the well toward the casing; a return pipe disposed co-axially within the cylindrical shell, wherein the arrangement of the casing and the return pipe form an annulus between the return pipe and the cylindrical shell, the inner volume of the return pipe being thermally insulated from the annulus; a plurality of centralizers disposed within the annulus, each of the plurality of centralizers comprising a first end and a second end, the first end of the plurality of centralizers connected to an inner surface of the shell and the second ends of the plurality of centralizers connected to an outer surface of the return pipe, the centralizers having a low profile to minimize hydraulic resistance to flow within the annulus; and wherein the plurality of support collars are configured to allow flow of a heat carrier between the inner surface of the well and the casing.
