“…However, an essential part of surfactants’ interfacial properties is the critical micelle concentration (CMC), which is a measure of the efficiency of a surfactant’s interfacial activity. A detailed discussion on the CMCs of SCA and SDS and the IFT reduction capability of both surfactants is presented in our previous report . SCA and SDS are shown to have almost the same CMCs of 0.233 and 0.229 wt %, respectively.…”

“…Amino acid-based surfactants are among the proposed alternative surfactants; yet, their investigation is limited, and the few studied showed less promising results. Nevertheless, our recent study on sodium cocoyl alaninate (SCA) showed that some classes of amino acid-based surfactants can offer promising recovery . This current study, therefore, proposes a combination of organic alkali, monoethanolamine (ETA), and sodium cocoyl alaninate (SCA) as an alkali–surfactant (AS) formulation.…”

The development of combinatory flooding has evolved over the years to utilize the synergies that come into play upon combining more than one chemical agent in a chemical flooding process. This study focuses on investigating the synergies that exist in combining monoethanolamine (ETA) and sodium cocoyl alaninate (SCA) as an alkali–surfactant (AS) formulation for the enhanced oil recovery process. A conventional formulation made of sodium carbonate (Na2CO3) and sodium dodecyl sulfate (SDS) was used for a comparative purpose. The proposed formulation proved to be compatible with the prepared hard brine. The ETA–SCA combination proved superior to Na2CO3–SDS in interfacial tension (IFT) reduction and wettability alteration. Addition of ETA to SCA synergistically reduced IFT to a low value of 4.73 × 10–2 mN/m at a surfactant concentration lower than the critical micelle concentration (CMC). ETA also played a synergistic role in improving the wetting power of SCA on quartz surface. The formulation also showed a high emulsifying ability owing to its superior IFT reduction capability. Static adsorption studies showed SCA to exhibit Langmuir-type adsorption behavior similar to SDS. The adsorption of SCA onto a sand surface was favorable, but ETA proved to reduce adsorption of SCA effectively at 0.3 wt %. The ETA–SCA and Na2CO3–SDS systems achieved additional oil recoveries of 31 and 25% original oil in place (OOIP) over conventional core flooding, respectively. The proposed AS formulation, therefore, showed better recovery potential in addition to its environmentally friendly nature.

“…Monoethanolamine (ETA) has proven to be one of the most promising organic alkalis that have undergone extensive studies [ 10 , 11 , 12 , 13 , 15 , 16 , 17 ]. Renewable resource-based surfactants have also been proposed as alternatives to petrochemical-based surfactants due to their high biodegradability and biocompatibility [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Surface-active ionic liquids (SAILs) have also been proposed for surfactant application in harsh reservoir conditions (high-temperature and high-salinity reservoirs) [ 28 , 29 ].…”

Combinatory flooding techniques evolved over the years to mitigate various limitations associated with unitary flooding techniques and to enhance their performance as well. This study investigates the potential of a combination of 1-hexadecyl-3-methyl imidazolium bromide (C16mimBr) and monoethanolamine (ETA) as an alkali–surfactant (AS) formulation for enhanced oil recovery. The study is conducted comparative to a conventional combination of cetyltrimethylammonium bromide (CTAB) and sodium metaborate (NaBO2). The study confirmed that C16mimBr and CTAB have similar aggregation behaviors and surface activities. The ETA–C16mimBr system proved to be compatible with brine containing an appreciable concentration of divalent cations. Studies on interfacial properties showed that the ETA–C16mimBr system exhibited an improved IFT reduction capability better than the NaBO2–CTAB system, attaining an ultra-low IFT of 7.6 × 10−3 mN/m. The IFT reduction performance of the ETA–C16mimBr system was improved in the presence of salt, attaining an ultra-low IFT of 2.3 × 10−3 mN/m. The system also maintained an ultra-low IFT even in high salinity conditions of 15 wt% NaCl concentration. Synergism was evident for the ETA–C16mimBr system also in altering the carbonate rock surface, while the wetting power of CTAB was not improved by the addition of NaBO2. Both the ETA–C16mimBr and NaBO2–CTAB systems proved to form stable emulsions even at elevated temperatures. This study, therefore, reveals that a combination of surface-active ionic liquid and organic alkali has excellent potential in enhancing the oil recovery in carbonate reservoirs at high salinity, high-temperature conditions in carbonate formations.

“…MEKC is a well-established technique for the enantiomeric separation of chiral compounds [21] [24] [25] [26] [30] [31] [32] [33] [34]. Amino acid-based surfactants are composed of a non-polar hydrocarbon chain and an amino acid head group [35]- [40]. The charge on the amino acid head groups can be greatly influenced by pH levels.…”
