Surfactant solutions for low-permeable polimictic reservoir flooding

[摘要] The paper presents the results of the study and development of new surfactants for flooding of low-permeable polymictic reservoirs. The developed composition allows considering the influence of reservoir rocks on a clay bond (to ensure clay-swelling inhibition), and on oil displacement (to reduce the interfacial tension within the oil-water-rock system).
