METHOD FOR ISOLATION OF MINE WORKINGS FROM INFLOW OF WATER CONTAINING OIL Russian patent published in 1994 - IPC

Abstract RU 2012775 C1

FIELD: mining industry. SUBSTANCE: method consists in injection of urea aqueous solution into oil-water containing fluids with oil n-alkanes. Urea solution is injected in amount equimolar to content of oil n-alkanes to fully fill isolation zone and to form clathrates. Urea is injected provided oil-water containing fluids have oil heavy fractions. EFFECT: higher efficiency and reliability of isolation due to clogging pores with formed clathrates and oil heavy fractions remaining after clathration.
