FIELD: oil and gas industry.
SUBSTANCE: method involves in-series pumping to formation of gel disperse system - GDS and stitched polymer system - SPS. At that, GDS pumping is performed in two stages using fresh water as a solvent at the first stage, and water with mineralisation level of not less than 15 g/l is used as a solvent at the second stage.
EFFECT: improvement of oil recovery and reduction of water content of the extracted products.
