Abstract
Anionic Surfactant Adsorption: Insight for Enhanced Oil Recover
Highlights
Oil is the most used nonrenewable source of energy in the world and this has led to the study of new processes for exploration and production of oil reservoirs
The purity of anionic surfactants, hydrocarbon chain and functional groups all these conditions play a rule in surfactant adsorption
All the results show that electrostatic bond between the kaolinite mineral and the anionic surfactant as the dominant adsorption mechanism and very weak hydrogen bond with the other clay mineral
Summary
Surfactant flooding is a known enhanced oil recovery technique used in the oil and gas industry for decades. The primary principle of surfactant flooding is to reduce interfacial tension, wettability between the oil, water and rock, a lot of attention on research has been devoted to this area of study but the problem is the economical factor due to the high rate of surfactant loss to rock formation and clay minerals, as a result of surfactant retention. This paper is to review the basic concepts of surfactant nature, minerology, electorlyte, temperature and pH as future guide lines in addressing the surfactant losses due to the adsorption
