... chemical agents, such as water, gas, caustic, water-alternated-gas injection, etc. The core sample for the study has been selected from the layer BH 4-5 of Eastern Siberia. Materials and methods OST 39-195-86 Oil. The method of estimating the water-oil displacement efficiency under laboratory conditions. Results The results of the experiments showed that water-alternated-gas injection and gas stimulation are more efficient in oildisplacement than other displacement agents. Сonclusions Gas injection ...

... Выводы С учетом влияния сжимаемости образцов керна на коэффициент вытеснения, последний увеличивался в диапазоне 15,66%-48,64%. For estimation of the displacement efficiency the results of the laboratory studies of core have been used as the background data. The estimation has been carried out with the use of petrophysical parameters, such as residual water saturation and the pore volume. Materials ...
