United States Patent Application 20190154010 (USPTO)
Applicant: Eavor Technologies Inc., Calgary, Canada.
The present invention relates to a method and apparatus for producing energy and more particularly, the present invention contains enhancements in segregated and integrated well loop circuits for generating geothermal power.
Methods and fluids for generating power with closed well loops in a geothermal environment. The loops may be segregated or non-segregated. Operation of the loop circuits is dynamically modifiable in subzero temperatures which contributes to higher and efficient power output. Specific working fluid compositions, including drag reducers, complement the efficiency together with the absence of casing within the loop for maximum thermal transfer between the formation and the working fluid.
