In surfactant flooding<\/em>, surfactants are injected into the reservoir to help increase oil recovery, one of which is by reducing the interfacial tension<\/em> (IFT) between oil and water. However, not all injected surfactants will continue to move with the fluid phase. Some surfactants may be retained within the porous media<\/em> through several mechanisms. Understanding surfactant retention<\/em> is important for evaluating how surfactants are transported through the rock and how retention can affect the efficiency of chemical<\/em> in Chemical Enhanced Oil Recovery<\/em> (EOR).<\/p>\n\n\n

What Happens to Surfactants in Porous Media<\/em>?<\/strong><\/p>\n\n\n\n

When surfactants flow through the rock, their molecules can interact with the rock surface and the fluids within the pores. These interactions can cause some surfactants to be retained within the porous media.<\/p>\n\n\n\n

Several mechanisms of surfactant retention<\/em> includes:<\/p>\n\n\n\n
