Sol-forming oil-displacing system intended to enhance oil recovery from deposits with difficult-to-recover reserves

The paper presents the results of laboratory tests of the sol-forming NINKA®-Z system intended to enhance oil recovery from deposits with difficult-to-recover reserves. The kinetic and rheological features of solation in the oil-displacing system have been investigated. A physical modeling of the oil displacement process was carried out under the conditions of a heterogeneous reservoir at a low temperature using the sol-forming NINKA®-Z system. The investigations have proved its high efficiency, and the system was recommended for pilot tests.
