Abstract:
1. The method to enhance oil shale, oil sand, asphaltic crude oil, or other high viscosity crude oil production by using a solar blackbody waveguide to heat these formations in situ comprising: collecting and concentrating solar flux by employing a system of mirrors, directing the solar flux from the system of mirrors into a shaft of a well drilled into a formation to be heated so that the solar flux travels in a lossless manner to the area of the formation to be heated within a reflective sleeve provided within a solar coil that serves as the casing for the shaft, and reflecting the solar flux successively in a lossy manner within the interior portion of the solar coil located within the formation to be heated so that the coil is heated by the solar flux and thereby heats the formation by conduction.
