Abstract
An in-situ oil shale production system used for economically mobilizing and extracting hydrocarbons in an underground oil shale deposit. The production system includes a plurality of injection wells, a plurality of production wells and a thermal energy carrier, called herein 'TECF'. The TECF is injected through the injection wells into a naturally occurring, highly-permeable zone. The highly-permeable zone is used to create a porous heating element. The porous heating element, at high temperatures in the range of 900 to 1300 degrees F., mobilizes and retorts the hydrocarbons in the porous heating elements. The hydrocarbons with the TECF then flow from the porous heating element through the production wells to the ground surface for refining. The surface area of the large porous heating element provides a means for economic, in-situ retorting of hydrocarbons from a carbon-rich, oil shale geologic formation.
