Abstract

A process for retorting and extracting sub-surface hydrocarbons. The process comprises drilling an energy delivery well extending from the surface to a location proximate a bottom of the hydrocarbons. The hydrocarbons are heated from the bottom to form a retort, the retort extending along a portion of the energy delivery well. A vapor tube is extended to a location proximate the retort, the vapor tube having an entrance corresponding to the region of the retort along the energy delivery well that is nearest the surface exit.
