Abstract
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.
Claims20
A method of generating power, comprising:
- providing a sealed closed well loop circuit having an inlet and an outlet connected with at least one lateral conduit within a geological formation and a first working fluid, said lateral conduit absent casing;
- providing a power generating circuit having a second working fluid, said circuit in thermal transfer communication with said well loop circuit;
- circulating said first working fluid and said second working fluid within the respective circuits;
- transferring heat from said first working fluid to said second working fluid;
- and
- generating power from recovered heat energy.
A method of generating power in a sealed closed well loop having an inlet well and an outlet well and at least one lateral conduit absent casing within a geological formation and power generating apparatus in operative communication with said well loop, comprising:
- providing a working fluid containing a mixture of polar and non-polar molecules which undergo a phase-change in the lateral portion of the well-loop;
- providing a power generating circuit for utilizing recovered energy from said working fluid;
- circulating said working fluid within said loop;
- and
- generating power from recovered heat energy.
A method of recovering heat in a sealed closed well loop having an inlet well and an outlet well and at least one lateral conduit absent casing within a geological formation and heat transfer apparatus in operative communication with said well loop, comprising:
- providing a working fluid circulating within said loop;
- and recovering heat energy for subsequent use.
