Summary: The low salinity water flooding (LSWF) technique is cost-effective and environmentally friendly, but its mechanisms are not yet clear. Recovery in LSWF depends on fluid/fluid and rock/fluid interactions. This study investigated both interactions and found different optimal conditions for improved oil recovery. Rock/fluid interaction showed an incremental recovery of 14%, while fluid/fluid interaction showed an incremental recovery of 7% over simple seawater injection. Results highlight the importance of considering both interactions and wettability alteration in LSWF design.

Summary: Controlled salinity water flooding, or engineered water flood, is a potential enhanced oil recovery (EOR) method that has been tested in laboratory and at pilot/field scale. However, there have been cases where this method failed to show its potential for EOR, mainly due to a lack of understanding of the underlying mechanism specific to each case.

Summary: A low salinity surfactant (LSS) system was developed to enhance the performance of immiscible surfactant alternating gas/CO2 (SAG) flooding in sandstone reservoir cores. LSS solutions showed positive impacts on various mechanisms responsible for enhanced oil recovery (EOR), including reducing surface and interfacial tension, altering wettability, improving CO2-foam stability, and decreasing surfactant adsorption.

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: We examined the stability of SiO2 and Al2O3 nanoparticles in both deionized water and low-salinity water. The stability was influenced by dispersion techniques and surfactant addition. SiO2 showed better stability due to its hydrophilicity, while Al2O3 tended to aggregate in low-salinity water. Various dispersion methods were applied to Al2O3, and the best stability was achieved with cationic and nonionic surfactants at pH 2.

Summary: Naturally fractured carbonate reservoirs are highly heterogeneous, with mineral precipitation affecting fluid flow behavior significantly in fractures. Mineral cementation can lead to partial blockage of fractures, reducing their flow capacity, but the matrix medium can enhance fluid flow in fractures to some extent.

Summary: Ionic liquids as drilling fluid additives have been successfully used to modify mud rheology, with the effectiveness depending on the length of the alkyl chain and the interaction between the ionic liquid and the clay. Research shows that intercalation of ionic liquids between clay layers alters clay structure and mud rheology. Factors like alkyl chain hydrophobicity, polarity, and solubility play a crucial role in modifying clay wetting and dispersion behavior, ultimately affecting mud filtration and rheological properties.

Summary: The use of ionic liquids as drilling fluid additives has been a topic of research, but their toxicity and non-environmentally friendly nature has shifted the focus to deep eutectic solvents as a more cost-effective and non-toxic alternative. Deep eutectic solvents have shown promising results in improving mud performance by interacting with clay particles. Characterization studies have revealed that the enhancement of mud rheology is achieved through alteration in clay orientation and particle dispersion.

Summary: ASP (Alkaline/Surfactant/Polymer) flooding is a promising technique, but emulsion stability is a key issue. The study found that AOS concentration above 100 ppm increased emulsion stability, while below 100 ppm it promoted water separation. The effects of sodium carbonate alkaline and GLP100 polymer on emulsion stability were less significant.

Summary: Ionic liquids are popular additives for drilling fluids, but they are costly and toxic. Deep eutectic solvent (DES) is a cheaper and non-toxic alternative. This research shows that adding DES to water-based mud delays the formation of hydrates, improves the rheology of the drilling fluid, and reduces filtrate volume and mud cake thickness. The improved mud rheology is attributed to the change in clay's size and structure due to interaction with DES.
