... 39-195-86 Oil. The method of estimating the water-oil displacement efficiency under the laboratory conditions. Results In this study the estimation of the displacement efficiency has been carried out with account for the impact that the core samples compressibility has on such parameters as residual watersaturation and the pore volume. The laboratory studies have shown the compressibility leads to the change in pore volume previously occupied by the residual water saturation. Сonclusions With account ...
