Abstract: In Alkaline-Surfactant-Polymer (ASP) flooding, mobility control is one of the important factors for improving tertiary oil recovery. It is achieved by using polymeric mobility control agent such as partial hydrolyzed polyacrylamide (HPAM). However, polymer is highly degradable when subjected to high temperature; high salinity and high shear rates. These limitations of polymer adversely restrict the extension of ASP in such reservoirs conditions. In order to overcome these limitations, Wormlike Micellar (WLM) solution can be studied as a potential alternative. This study presents a review on application of WLM solution as mobility control agent for chemical EOR. It discusses the current limitations with existing polymers, comparison between WLM and polymerr.
