Emulsion flooding has been proved to be an effective chemical enhanced oil recovery (CEOR) method. The performance of this technique is strongly dependant on the formulation of the emulsion slug. Toachieve the best formulation, different approaches have been introduced in the literature. Nevertheless,a systematic workflow containing the method(s) of the design of experiments (DOEs) has not beenreported as yet. In this paper, we developed a workflow which is comprised mainly of three stages. In thefirst place, the phase behavior experiments of sodium dodecyl sulfate (SDS)/water/diesel (as an efficientand economic hydrocarbon phase)/salt system were carried out using response surface methodology(RSM) to model and optimize the emulsification process. The second stage was followed by thecharacterization of optimum formulation in terms of rheological behavior and particle size distribution. Finally, microvisual and core-flood displacement tests were performed to evaluate the efficacy ofemulsion flooding to recover the residual oil bypassed or trapped after water flooding. This paperpresents the results of experiments done in different stages of the proposed workflow. The resultsdemonstrate the high potential of emulsion formulated systematically by DOE approach to increase oilrecovery factor

The positive feedback from previous studies has confirmed the high performance of microemulsionflooding. However, there are few researches assessing this efficient method in carbonates reservoirs,particularly at high temperature. This paper attempts to fill the gap. Furthermore, biodiesel is introducedand evaluated as a new hydrocarbon source of mixture. For this purpose, phase behavior of surfactant/brine/biodiesel/co-solvent was systematically studied using response surface methodology to find theoptimum formulation. Thereafter, optimized microemulsion was characterized in terms of particle sizedistribution, zeta potential, electrical conductivity, polarized light microscopy, surface tension,interfacial tension, and viscosity. Finally, oil recovery tests comprising spontaneous imbibition, contactangle, core-flood and microvisual experiments were conducted to examine the potential of optimumformulation for chemical enhanced oil recovery (CEOR) purpose in carbonates. Experiments of differentstages were carried out at elevated temperature (75 8C). Employing optimal microemulsion, 20.0%original oil in place (OOIP) in spontaneous imbibition and 6.4% OOIP in core-flood tests were tertiaryadded to oil recovery. The results of this study illustrate the efficacy of proposed formulation to increaseoil recovery factor of carbonate formations.
