The use of surfactants to increase oil recovery

The use of surfactants is not only one of the most effective methods of increasing oil recovery, but also gives the maximum effect if it is introduced from the beginning of development. The first attempts to use emulsions in the oil industry were made in the early 70s, but because of the high cost of reagents and a limited range of surfactants, emulsion systems found limited use. As domestic and international experience shows, effective development of reserves is impossible without the massive use of reservoir stimulation methods. when, starting from the stage of progressive watering of products, the main role is played by flow-deflecting technologies using surfactants
