Summary: The surfactant EOR is considered a promising approach for enhancing oil recovery due to the changing energy supply and demand and the non-renewable nature of world oil reservoirs. However, surfactants face challenges such as high adsorption, low stability, and poor performance in harsh conditions like high temperature, high salinity, and dense carbonate rocks. There is currently no established procedure or framework for systematically selecting the best surfactant for EOR in dense carbonates.

Summary: Due to the heavy reliance on crude oil, it is crucial to develop enhanced oil recovery techniques for better reservoir production and lifespan. Carbonate reservoirs make up more than half of the global oil reserves, but their recovery is challenging due to complex pore structure, oil-wet or mixed-wet rocks, and harsh temperature and salinity conditions. This work presents a significant contribution in exploiting these reservoirs through the design of a new formulation with low interfacial tension and reduced adsorption on carbonate rocks, resulting in promising oil recovery.

Summary: Surfactant-based oil recovery processes are used to lower interfacial tension and change the wettability of rock in immiscible displacement processes. The key factors affecting this process are temperature, salinity, pH, surfactant concentration, and adsorption. Chemical enhanced oil recovery (cEOR) processes combine surfactants with other chemicals to exploit their synergy. This review study categorizes the role and displacement mechanisms of surfactants and discusses key factors for analyzing fluid displacement in porous media.

Summary: In polymer flooding, there is no positive correlation between the viscosity of polymer displacement agents and displacement performance. While polymer with sheet-net structure has the ability to increase viscosity, it has poor compatibility with reservoir rock pore throat structure. On the other hand, heterogeneous weak gel system has higher adsorption and retention capacity, making it easier to establish seepage resistance in porous media.

Summary: This study investigates the use of different types of cationic, anionic, and nonionic surfactants to improve oil recovery in tight carbonate cores from the Middle Bakken Formation in the Williston Basin. The findings suggest that core samples with more clay and larger pore diameters exhibit higher oil recovery. Anionic surfactants appear to yield better oil recovery in tight Bakken rocks, possibly due to their higher carbonate mineral concentrations. This study enhances our understanding of the impacts of mineral composition, pore size, and surfactant types on oil recovery in tight carbonate rocks.

Summary: Surfactants increase displacement efficiency by reducing interfacial tension and altering rock wettability. However, conventional surfactants precipitate under harsh reservoir conditions, limiting their efficiency. Zwitterionic surfactants have good salinity and thermal tolerance and were investigated for their behavior at the oleic-aqueous interface. Experimental results show that the synthesized betaine-type surfactants demonstrated exemplary stability and efficiency for EOR.

Summary: A novel synthesized magnetic surfactant was found to be effective in inhibiting shale swelling in drilling mud. The addition of 0.4 wt% magnetic surfactant significantly reduced linear swelling by interacting with bentonite particles and intercalating into bentonite clay layers. It also increased fluid loss and decreased rheological parameters. Thus, the magnetic surfactant shows great potential as a drilling fluid additive.

Summary: Surfactants are commonly used in carbonate hydrocarbon reservoirs for enhanced oil recovery. This study focuses on injecting a single component surfactant to mitigate the risk of chromatographic and phase separation. The results show that the single component surfactant alone can achieve high oil recovery without the need for additional cosolvents or cosurfactants, and injecting a polymer can further improve the oil recovery.

Summary: This study evaluated a locally synthesized gemini surfactant with high stability, salt tolerance, and CEOR potential for reducing interfacial tension and enhancing oil recovery. The study found that as the gemini surfactant concentration increased, the interfacial tension also increased. The lowest interfacial tension value of 0.12 mN/m was obtained at a concentration of 0.0005 wt%, while the highest value of 0.84 mN/m was recorded at concentrations of 0.5 and 1 wt%. The highest ultimate recovery of 50.26% was achieved at a concentration of 0.005% GmS.

Summary: This study investigated the phase behavior of viscoelastic surfactant (VES)/crude oil and VES/squalene systems, and examined the effects of salinity, concentration, and temperature on the volume fraction phases and solubilization ratios. The results showed that in the VES/crude oil system, the emulsion volume decreased with increasing salinity and surfactant concentration, while the temperature had a mixed effect. In the VES/squalene system, the lowest emulsion value was observed at specific salinity, temperature, and VES concentration. Equal solubilization was achieved under certain conditions in both systems.

Summary: This study presents a promising solution for addressing wellbore instability caused by the expansion of shale formations in drilling operations. Researchers have explored the potential of graphene as a shale swelling inhibitor and fluid loss controller, but its practical application has been hindered by settling and limited dispersion. The study introduces a low-cost graphene prepared through electrochemical exfoliation, which is combined with a natural biopolymer to create a nanocomposite. The nanocomposite, known as electrochemically exfoliated graphene-modified Gum Arabic (GrO-ArG), demonstrates strong dispersion, stable dispersion in different pH and salinity solutions, and prominently reduces linear swelling and fluid loss in water-based drilling muds.
