FIELD: oil and gas industry.
SUBSTANCE: method of producing oil technogenic depost in the lithosphere comprises the drilling of injected and extraction wells to the depth of the lithosphere with pressure of 8-10 MPa, temperature of 125-200°C and reservoir porosity of 10-20%, feeding non-treated urban waste waters to the injected wells with organic matter content not less than 100-300 mg/l and volume of not less than 20 thous. m3/day, carrying out a hydraulic fracturing, maintaining wastes to form a technogenic oil and its subsequent extraction to the daylight surface. Drilling of wells is carried out at a distance calculated based on the rate of organic water migration and a period of technogenic oil synthesis.
EFFECT: method allows to obtain industrial quantities of oil while simultaneously utilise human livelihood wastes.
