Use of Petrochemical Products for Gas Shutting in Oil-Gas Reservoirs
2018
A new method for preventing gas breakthroughs to producing well bottom during oil recovery from oil-gas condensate deposits, which enhances the efficiency of gas recovery technologies, is proposed. The method consists in use of hydrophobic gas shutting compositions based on furnace (residual fuel) oil. Filtration studies (physical modeling) of the gas shutting process were conducted for the proposed compositions. The gas breakthrough was simulated using permeable bulk porous media or permeable cores of productive bed of the reservoir.
