Surfactant flooding experimental study

This chapter covers the fundamentals of surfactant flooding, which include microemulsion properties, phase behavior, interfacial tension, capillary desaturation, surfactant adsorption and retention, and relative permeabilities in surfactant flooding. It provides the basic theories for surfactant flooding and presents new concepts and views about capillary number (trapping number), relative permeabilities, two-phase approximation of the microemulsion phase behavior, and interfacial tension. This chapter also presents an experimental study of surfactant flooding in a low-permeability reservoir. 

Generally, chemical flooding is conducted in a high permeability reservoir. This section describes an experimental study of the application of surfactant flooding... 

Surfactants in Remediation. Although surfactant use in enhanced oil recovery has been explored in some detail, its use as a remedial flooding technique is still in the preliminary experimental stages, and few studies are available in the literature to date. Examples of some studies are discussed here.
