“…According to the reports mentioned by various researchers, higher HLB values are more suitable for reservoirs with a high salinity. Surfactants with high HLB values are also suitable for attaining middle-phase microemulsion (Winsor III) . Thus, it is possible to move HLB toward the target values by using cosurfactants, which can be several future research directions.…”

“…Since these materials are expensive, the critical consideration is the economic impact of biosurfactant loss and adsorption. 5,6,32,33 In this research work, due to the phenomenon of adsorption of surfactant on rock, 34,35 the rhamnolipid concentration was considered higher than the CMC. As anionic surfactants such as rhamnolipids are known as high-temperature-resistant surfactants, 36 experiments were also performed at 25 °C.…”

One of the main problems faced by engineers in EOR is not having the conditions for the formation of Winsor III (ultralow IFT), which causes a reduction in oil recovery efficiency and also an increase in costs. Therefore, this research tries to fill this gap through the smart injection of biosurfactants into oil reservoirs. To simulate Winsor III, the aqueous phase [NaCl (10,000−150,000 ppm) and rhamnolipid (300 mg/L)] and crude oil (API°31) were mixed in a 1:1 ratio (v/v) in glass test tubes. In this work, rhamnolipid biosurfactant was first produced by Pseudomonas aeruginosa PTCC 1340 and afterward confirmed using FTIR, NMR, and TLC analyses. The produced rhamnolipid reduced IFT from 28.4 (oil phase/brine) to 1.8 mN/m, and the slab's wettability changed from strongly oil-wet (θ = 146.2°) to intermediate-wet (θ = 92.4°). Our results showed that ultralow IFT (Winsor III) was obtained at about 0.015 mN/m under conditions of salinity of 40,000 ppm, rhamnolipid concentration of 300 mg/L, and ambient temperature. Core flooding tests in carbonate cores led to substantial tertiary recovery of 18.1 and 14.8% of OOIP (Original Oil in Place) under Winsor III and II, respectively, over conventional water flooding. This increase in EOR can be due to the increase in the capillary number. According to the proposed novel method in this research, the capillary number of Winsor III increased about 8 times compared to that of Winsor II through the smart injection of biosurfactant into the core. Our results are an initial step to help researchers through smart injection in oil reservoirs to provide the possibility of being in Winsor III conditions to reach the ultralow IFT and subsequently increase oil recovery efficiency.

“…Additionally, they can modify the wettability of the rock, leading to increased oil recovery. 14,19,20 Injecting low salinity water (LSW) also has demonstrated advantages such as reducing capillary pressure and oil−water IFT and changing rock wettability to a water-wet state, which in turn enhances the flow of oil. 21,22 Nevertheless, various challenges arise during field applications that can negatively impact the effectiveness of EOR materials.…”

In recent years, chelating agents have garnered increasing attention due to their unique capabilities in addressing challenges associated with chemically enhanced oil recovery materials. Most previous studies have primarily focused on examining the influence of chelating agents on rock–fluid interactions. However, their effects on fluid–fluid interactions, specifically on interfacial tension (IFT) characteristics under various conditions, remain relatively unknown. This study investigates the effect of crucial reservoir parameters on the performance of ethylenediaminetetraacetic acid (EDTA) chelating agents in the IFT between crude oil and brine. Furthermore, the study evaluated the impact of varying concentrations of this agent on rock wettability alteration, zeta potential, and spontaneous imbibition. The results illustrated that introducing EDTA at high concentration into seawater (SW) solution reduced the IFT by 85%. Additionally, while higher pH levels contributed to IFT reduction due to increased hydroxyl ions, excessive salinity levels resulted in elevated IFT. Raising the temperature from 30 to 75 °C further decreased the IFT, changing the IFT for optimal EDTA concentration from 20.43 to 2.56 mN/m (∼88% reduction). The changes in zeta potential and contact angle measurements indicated that solutions of 5 and 7 wt % EDTA shifted rock wettability from oil-wet to strongly water-wet, resulting in the wettability alteration index of 1.01 and 1.02, respectively. Inductively coupled plasma analysis, on the other hand, revealed substantial chelation of metal ions from both the solution and rock when EDTA was added to the rock/SW system. This resulted in a significant increase in Ca2+ ions and a decrease in Mg2+ ions, attributed to the multi-ion exchange phenomenon.
