The offered work covers the results of the theoretical, experimental and field works of nowel reservoir stimulation technologies providing in-situ generation of carbon dioxide (СО2) with the purpose of oil recovery efficiency increase.
Results of experimental researches describing a new way of in-situ generation of gas-liquid slug during displacement of residual oil reserves are shown.
The methodical approach to the estimation of quantitative and qualitative influence of technological features of difficult oil reserves on the final recovery factor is offered.
