There is provided a portable oil extraction system comprising one or more high heat energy generators that supply high heat energy to an underground oil-rich zone. Each heat energy generator comprises a chamber for gasifying used rubber tires, waste oil, coal or other combustible materials for the production of volatile gases and high energy heat. Exhaust gases from the heat generator are piped underground into a zone of oil-rich material such as oilsands, oilshale, or contaminated soil to heat the oil-rich material therein to vaporize the hydrocarbons. Vacuum pressure withdraws the vaporized hydrocarbons from the underground oil-rich zone. The vaporized hydrocarbons are condensed and collected within a forced-air condenser for reuse. An optional second stage refrigeration unit condenses any residual vaporized hydrocarbons that may be missed by the forced-air condenser. No water or chemical additives are used in this environmentally benign process.
