FIELD: wasteless technology of oil and oil products extraction from oil containing sand, sand-argillaceous grounds. SUBSTANCE: method includes extraction of oil from oil-containing ground by circulating carbonic acid gas under pressure, separation of extracted products from gas and its repeated return to extraction stage. Extraction with the help of carbonic acid gas is effected at temperature and pressure corresponding to gas critical state. EFFECT: higher degree of extraction of oil and oil products, reduced duration of process, provided safety of process due to development of ecologically clean wasteless technology. 1 tbl
