“…Among various EOR methods, the surfactant flooding has a high potentiality in displacing the residual oil toward the production wells (Qi et al 2014). Capillary forces have a significant role in causing oil to be trapped in the reservoir (Ahmadi et al 2014;Ali et al 2018a), which is mostly happened in carbonate oilwet reservoir (Ahmadi and Shadizadeh 2013;Gupta et al 2009;Jarrahian et al 2012;Lu et al 2014;Pordel et al 2012;Seethepalli et al 2004;Bortolotti et al 2010). Since waterflooding has shown the low performance in this kind of reservoirs, IFT reduction and wettability alteration are the main EOR mechanisms of increasing the oil recovery (Golabi et al 2009;Ali et al 2018b).…”

Capillary and interfacial forces are of great influences of trapping hydrocarbon in porous media after primary and secondary recovery processes. The trapped crude oil in the reservoir can be mobilized and produced by reducing these forces. Thus, surfactant flooding, as a main enhanced oil recovery (EOR) method, is usually applied to reduce the interfacial tension (IFT) of crude oil-water system in porous medium and improves the oil recovery. This study focused on the effect of [C 8 Py][Cl] and [C 18 Py][Cl] ionic liquids (ILs), as a new family of surfactant, in combination with various salts including sodium chloride, potassium chloride, magnesium sulfate and potassium sulfate on IFT reduction. EOR injection solutions were prepared from mixing the ILs at different concentrations of 100, 250, 500 and 1000 ppm with the salts ranging from 500 to 80,000 ppm. Obtained results showed that the minimum IFT value from both ILs was achieved when the concentration of the ILs was about 1000 g/mL, and the concentrations of KCl, K 2 SO 4 , MgSO 4 and NaCl were 1000, 2000, 500 and 80,000 ppm, respectively. The minimum IFTs were achieved when NaCl and ILs concentrations were the maximum and MgSO 4 concentration was the minimum.

“…Consumption of oil, the most common energy source, has been increased in the world and discovery of new oil reservoirs has been reduced due to exploration difficulties (Ali et al 2018a). Thus, the oil industry focuses more on increasing the production from the currently producing reservoirs using different oil recovery methods including primary, secondary, and tertiary recovery processes (Ali et al 2018b).…”

Surfactant flooding is an important technique used to improve oil recovery from mature oil reservoirs due to minimizing the interfacial tension (IFT) between oil and water and/or altering the rock wettability toward water-wet using various surfactant agents including cationic, anionic, non-ionic, and amphoteric varieties. In this study, two amino-acid based surfactants, named lauroyl arginine (l-Arg) and lauroyl cysteine (l-Cys), were synthesized and used to reduce the IFT of oil-water systems and alter the wettability of carbonate rocks, thus improving oil recovery from oil-wet carbonate reservoirs. The synthesized surfactants were characterized using Fourier transform infrared spectroscopy and nuclear magnetic resonance analyses, and the critical micelle concentration (CMC) of surfactant solutions was determined using conductivity, pH, and turbidity techniques. Experimental results showed that the CMCs of l-Arg and l-Cys solutions were 2000 and 4500 ppm, respectively. It was found that using l-Arg and l-Cys solutions at their CMCs, the IFT and contact angle were reduced from 34.5 to 18.0 and 15.4 mN/m, and from 144° to 78° and 75°, respectively. Thus, the l-Arg and l-Cys solutions enabled approximately 11.9% and 8.9% additional recovery of OOIP (original oil in place). It was identified that both amino-acid surfactants can be used to improve oil recovery due to their desirable effects on the EOR mechanisms at their CMC ranges.

“…3.2.2 Flooding tests at 1 wt% salinity. According to Table 2, the uids injected in tests 10,11,16, and 17 (central points) as well as in 4 and 9 have equal salinity and BS concentration (1wt% and 80 ppm, respectively); however, they differ in NP concentrations, which are 0, 50, and 100 ppm for test 9, central 31 The acidic components present in the crude oil contain many heteroatoms such as oxygen. Therefore, the used crude oil sample with TAN value of 0.46 mg KOH/g oil is considered a nearly acidic type with a considerable amount of heteroatoms.…”

“…9,[13][14][15] Nowadays, nanotechnology has attracted much attention for applications in EOR to produce more oil from reservoirs. Numerous studies conrm that NPs can alter the wettability characteristics of rocks to more water-wet conditions, [16][17][18] reduce IFT, 19,20 and function effectively in oil recovery. 21,22 According to Ragab and Hannora, 23 silica NPs improve oil recovery due to reduction in IFT and increase in the viscosity of the injected solution.…”
