  • Patent number: 9897394
    Abstract: Techniques for subsurface thermal energy storage of heat generated by concentrating solar power enable smoothing of available energy with respect to daily and/or seasonal variation. Solar thermal collectors produce saturated steam that is injected into a producing or wholly/partially depleted oil reservoir that operates as a heat storage reservoir. Some of the saturated steam generated by the collectors is optionally used to generate electricity. Heat is withdrawn from the reservoir as saturated steam and is used to operate an active thermal recovery project (such as a producing thermally enhanced oil reservoir) and/or to generate electricity. Withdrawn heat is optionally augmented by heat produced by firing natural gas. The reservoir is optionally one that has been used for thermally enhanced oil recovery and thus is already warm, minimizing heat losses.

  • Patent number: 9512677
    Abstract: A process is shown to efficiently drill multiple, short-length, medium-radius lateral holes from a vertical well shaft. The disclosed process may be performed without the need to repeatedly pull down-hole equipment for every lateral hole drilled so as to make the lateral hole drilling process efficient. A heat pipe assembly is shown inserted into each drilled hole. The disclosed drilling and heat pipe insertion may be performed multiple times at a given vertical depth location in the well shaft. The process may be performed without the need to repeatedly pull down-hole equipment for insertion of multiple heat pipes at a same vertical level in the well level for each lateral hole drilled at that level so as to make for an efficient heat pipe insertion process. The described process may be performed multiple times at a large number of vertical depth locations.

  • Patent number: 9404480
    Abstract: A closed-loop, solid-state system generates electricity from geothermal heat from a well by flow of heat, without needing large quantities of water to conduct heat from the ground. The present invention contemplates uses for depleted oil or gas wells and newly drilled wells to generate electricity in an environmentally-friendly method. Geothermal heat is conducted from the Earth to a heat exchanging element to heat the contents of pipes. The pipes are insulated between the bottom of the well and the surface to minimize heat dissipation as the heated contents of the pipes travel to the surface.
