PROCEDURE AND DEVICE FOR THE OPTIMAL UTILIZATION OF CARBON RESOURCES SUCH AS OIL FIELDS, OIL SHALES, OIL SANDS, COAL, AND CO2

摘要

A method and system are disclosed for recovering fossil fuel from a carbon deposit site, the method comprising (a) driving several boreholes through the earth's crust to depths below the surface at which supercritical conditions predominate, so that they are spaced from one another in a lower borehole region, and connected there to one another through to form a geo-heat exchanger resulting in creation of a supercritical geo-steam system; (b) injecting fluid into at least one of the boreholes, to convert the injected fluid into a supercritical fluid, and extracting the supercritical fluid through other of the boreholes; and (c) injecting the extracted supercritical fluid into the carbon deposit site to dissolve hydrocarbons contained therein, and transporting the supercritical fluid containing the hydrocarbons to the surface for recovery.
