FIELD: oil and gas industry.
SUBSTANCE: invention relates to method of hydrocarbons recovery from oil-bearing sands. Method includes oil-bearing sands supply to heating device and for oil-bearing sands heating in the heating device, where the heating device is extraction column where heating is ensured by means of the appropriate transporting fluid heated by sun energy collected by means of the optical concentric systems creating heated transporting fluid that acts as hot extracting fluid. At that specified extracting fluid is at supercritical phase, and extraction can be performed by modification of the conditions as per temperature and pressure to achieve the subcritical conditions.
EFFECT: method ensures energy saving from mineral sources and reduces harmful impact to environment.
