“…Among all cEOR methods, surfactant flooding is the most effective chemical EOR method having the greatest potential to improve oil recovery. During surfactant flooding, the force that lowers the interfacial tension (IFT) and alters the wettability tends to allow the trapped crude oil in the pore spaces to be displaced (Howe et al 2015;Manshad et al 2016;Ahmadi and Shadizadeh, 2018;Hanamertani et al 2017;Olayiwola and Dejam 2019a, b;Najimi et al 2019).…”

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.

“…3,4 Moreover, there is a great interest in ILs as green corrosion inhibitors because of their large number of advantages, such as low toxicity, high thermal steadiness, low volatility, elevated ionic conductivity, and great action as corrosion inhibitors. [5][6][7][8] Among these features of ILs, their very small vapor pressure (will not vaporize), non-polluted environmentally friendly nature are attractive and make them less harmful as metal corrosion inhibitors. The metal corrosion inhibited by PILs is because of their adsorption on the iron surface.…”

“…To this end, studies have suggested surfactant screening and selection by surface charge to be matched to specific reservoir rock as a means of reducing surfactant adsorption in reservoirs. More recently, the use of low-cost sacrificial agent (such as polyelectrolytes and ionic liquids) evolved, has been prodigiously researched, and is being exploited for reducing surfactant adsorption in reservoirs [8,83].…”

Despite the progress made on renewable energy, oil and gas remains the world's primary energy source. Meanwhile, large amounts of oil deposits remain unrecovered after application of traditional oil recovery methods. Chemical enhanced oil recovery (EOR) has been adjudged as an efficient oil recovery technique to recover bypassed oil and residual oil trapped in the reservoir. This EOR method relies on the injection of chemicals to boost oil recovery. In this overview, an up-to-date synopsis of chemical EOR with detailed explanation of the chemicals used, and the mechanism governing their oil recovery application have been discussed. Challenges encountered in the application of the various conventional chemical EOR methods were highlighted, and solutions to overcome the challenges were proffered. Besides, the recent trend of incorporating nanotechnology and their synergistic effects on conventional chemicals stability and efficiency for EOR were also explored and analysed. Finally, laboratory results and field projects were outlined. The review of experimental studies shows that porescale mechanisms of conventional chemical EOR is enhanced by incorporating nanotechnology, hence, resulted in higher efficiency. Moreover, the use of ionic liquid chemicals and novel alkaline-cosolvent-polymer technology shows good potentials. This overview presents an extensive information about chemical EOR applications for sustainable energy production.
