Method for on demand power production utilizing geologic thermal recovery

A method for providing on demand power to an end user with a well system having an inlet well, an outlet well in a thermally productive geologic formation, comprising:

• forming a closed loop with a power generation device operatively connecting said inlet and said outlet;
• circulating a working fluid in said loop with a predetermined residency time to thermally load circulating working fluid through conduction from said formation;
• modulating the flow rate of thermally loaded working fluid within said loop for power generation based on user demand;
• interconnecting said inlet well and said outlet well with a plurality of interconnecting sections in a predetermined pattern within said formation;
• and
• selectively modulating circulation of said working fluid within predetermined sections of said plurality of interconnecting sections of said well system to oscillate thermal output from thermally charged working fluid about a characteristic predetermined potential thermal output capacity of said formation, where the averaged oscillated thermal output substantially equates with said predetermined potential thermal output capacity of said formation.

A method for providing on demand power to an end user, comprising:

• providing an inlet well, an outlet well and an interconnecting section between said inlet well and said outlet well and being disposed within a geologic formation having a predetermined potential thermal output capacity, said formation having a temperature of at least 90° C.;
• connecting said outlet well to a power generation device to recover energy from the well arrangement in a closed loop between the wells and the power generation device;
• and
• circulating a working fluid within said 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.
