Design and Evaluation of Efficient Microemulsion System for Chemical EOR

Shehzad-Ahmed , K.A. Elraies and Shuaib Ahmed Khalwar

Microemulsion behavior is an important aspect in chemical EOR because these can be used as an indicator for ultra low interfacial tension. At optimal salinity, type III microemulsion begins to form by solubilizing equal volume of aqueous phase and oil phase in the middle phase. However, salinity lower or higher than optimal causes significant increase in the interfacial tension, resulting in insufficient displacement efficiency. In this study, the behavior of microemulsion is investigated experimentally. Type III microemulsion were generated at different salinities using surfactant, co-surfactant, alcohol and crude oil to form gel and liquid crystal free clear microemulsion. As a result, alcohol alkoxy sulfates has shown good performance in term of solubilization for light oil and low temperature conditions. Effect of varying surfactant, co-surfactant and co-solvent concentration on microemulsion parameter has been presented. This systematic approach helps in efficient formulation screening and optimization of chemical EOR formulation in order to achieve ultra low interfacial tension between the residual oil and injection water.
