Abstract

A system for geothermal heating comprising: a forced geothermal circuit in communication with a well bore; a well bore heat exchanger; a multilateral channel; a channel casing design; and a pump. A method for geothermal heating comprising: passing a fluid into a thermal circulation system; passing the fluid into a well bore heat exchanger; heating the fluid; passing the heated fluid through a multilateral channel comprising a multilateral channel design casing; and passing a reservoir fluid and the fluid into a heat exchanger. A method for a loop recovery process comprising: passing a circulation fluid into a system for geothermal heating; passing the circulation fluid into a well bore heat exchanger; heating the circulation fluid; passing the heated circulation fluid out of the system for geothermal heating; passing the heated circulation fluid through a heat exchanger of an organic Rankine cycle; and cooling the circulation fluid.

Claims (16)

1 . A system for geothermal heating, the system comprising:

a vertical geothermal well bore;

a thermal circulation system disposed within said vertical geothermal well bore;

a sidetrack borehole in communication with said vertical geothermal well bore;

a well bore heat exchanger comprising an annulus and a heat exchanger;

said annulus disposed around said heat exchanger to form an annulus space;

said well bore heat exchanger disposed above said sidetrack borehole and extends horizontally from the vertical geothermal wellbore;

said sidetrack borehole comprising a side track extending horizontally at the end of said vertical geothermal well bore;

said heat exchanger configured to receive a circulation fluid;

said annulus space configured to receive a reservoir fluid exiting from said sidetrack;

and

said sidetrack configured to receive the reservoir fluid exiting from the annular space.

2 . The system of claim 1 further comprising a pump.

3 . The system of claim 1 wherein said circulation fluid comprises brine.

4 . The system of claim 1 wherein said circulation fluid comprises carbon dioxide.

5 . The system of claim 1 wherein the system for geothermal heating is in communication with an organic Rankine cycle.
