Surfactant-enhanced alkaline flooding for light oil recovery. [Annual report], 1993--1994
In this report, we present the results of our experimental and theoretical studies in surfactant-enhanced alkaline flooding for light oil recovery. The overall objective of this work is to develop a very cost-effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12.0) for ultimate spontaneous emulsification and ultralow interfacial tension. In addition, we have (1) investigated the effect of surfactant on the equilibrium and transient interfacial tension, (2) investigated the kinetics of oil removal from a silica surface, and (3) developed a theoretical interfacial activity model for determining equilibrium interfacial tension. The results of the studies conducted during the course of this project are presented.
