Abstract: A method includes flowing, in a closed loop geothermal well residing in a target subterranean zone, a first heat transfer working fluid and flowing, in the geothermal well, a second working fluid from the surface inlet to the downhole location of the geothermal well. The second working fluid resides upstream of the first heat transfer working fluid. The second working fluid includes a fluid density greater than a fluid density of the first heat transfer working fluid. The method also includes circulating, in the geothermal well, the second working fluid pushing, with the second working fluid, the first heat transfer working fluid toward a surface outlet of the geothermal well. The method also includes collecting energy from the mobilized first heat transfer working fluid received at the surface outlet of the geothermal well.

Abstract: Methods for providing on demand power to an end user in a variety of embodiments are disclosed. Closed loop thermal recovery arrangements are disposed within a geologic formation having a predetermined potential thermal output capacity. A power generation device is incorporated in the loop to recover energy. A working fluid is circulated within the loop at varying flow rates to oscillate thermal output about the predetermined potential thermal output capacity, to produce on demand power where the average thermal output may equal the predetermined potential thermal output capacity. Integrations with intermittent renewable energy sources are provided which optimize performance and distribution.
