Microemulsion-enhanced displacement of oil in porous media containing carbonate cements

Abstract: The impact of rock characteristics on the complex fluid-rock interactions is investigated  MEs enhance the immiscible displacement (or mobilization) of NAPL by decreasing IFT and oil droplet size  MEs promote the desorption of NAPL from rock surfaces (or solubilization) thereby altering their wettability  At low concentration, MEs outperform surfactants in rocks containing carbonate cements

“…The detailed preparation procedures are provided in previous studies. 8,9,51 In order to synthesize the SiO2 NP in-situ at the d-limonene/water interfaces in ME, we selected tetraethyl orthosilicate (>99%, Sigma Aldrich) as the oil-soluble precursor. It was first dissolved in dlimonene and then the mixture was used as the hydrocarbon phase to prepare surfactant-stabilized ME following the procedure described previously.…”

“…6,7 The performance of surfactants can be further enhanced by putting them into microemulsified state. 8,9 Microemulsions (MEs) are composed of water, hydrocarbon, and amphiphiles, which are optically isotropic and thermodynamically stable liquid solutions. 10 They differ from ordinary emulsions in that they can be prepared with little or no input of mechanical energy.…”

“…Compared to the high-pressure of water injection, low water displacement efficiency, and low ultimate recovery efficiency of water flooding [1][2][3][4], the surfactant flooding can reduce the threshold pressure gradient and injection pressure, increase the water injection rate which expands the swept volume, reduce the interfacial tension, and improve the displacement efficiency [5][6][7][8]. According to the surfactant concentration in the injection system, the surfactant flooding is divided into active water system (C s < 1%) and microemulsion system (C s � 3%∼5%) [9][10][11][12][13]. Because of the peculiarities of ultra-low interfacial tension and better mobility control, the latter one has become the hotspot in enhanced oil recovery of low-permeability reservoir.…”

“…Their effectiveness in modifying wettability and altering interfacial tension (IFT) is directly proportional to the oil recovery factor during the spontaneous imbibition process (Alvarez et al, ). Moreover, the surfactant structural make‐up can affect the displacement of oil recovery (Qin et al, ). This work extends those studies to include designing immiscible solvent‐based microemulsion solutions that can impart surface modifications to enhance oil recovery.…”
