Summary: Surface wettability plays a critical role in oil recovery and the displacement efficiency of viscous oil is greatly influenced by the wettability of the porous network. Hydrophilic surfaces promote higher oil recovery and result in a more efficient displacement pattern compared to hydrophobic surfaces.

Summary: This paper provides a systematic review of the literature on surfactant-based chemical-enhanced oil recovery (EOR) methods, focusing on performance evaluation and application potential. It is found that surfactant-based formulations can increase oil recovery by reducing interfacial tension, altering surface wettability, enhancing aqueous penetration, improving oil mobility, and promoting spontaneous imbibition. Laboratory experiments and field tests have confirmed the feasibility of chemical EOR and provided improvement schemes and future research directions.

Summary: The study investigated the influence of different injection schemes on the enhanced oil recovery (EOR) of heterogeneous phase combination flooding (HPCF) after waterflooding. Results showed that the alternating injection (AI) scheme had the highest EOR, while the simultaneous injection (SI) scheme had the least. Visual flooding experiments also confirmed that the swept area of HPCF under the AI scheme was higher than that of the SI.

Summary: This research proposes a new empirical scaling equation to predict oil recovery by modified salinity imbibing brines in limestone rocks. By considering two critical aspects and analyzing test data from various limestone samples, the equation is more realistic and applicable to reservoir conditions.

Summary: This study proposes three hybrid nonthermal enhanced oil recovery (EOR) techniques to recover viscous oils in shallow reservoirs on the Alaska North Slope. The coreflooding experiments and tests conducted demonstrate that these techniques have better performance in reducing residual oil saturation compared to traditional methods. The use of solvent injection results in oil swelling and viscosity reduction, while decreasing the salinity of injected brine benefits the water flooding process.

Summary: This article explores the impact of high and low salinity water flooding on oil transport in porous media, finding that salinity change plays a crucial role in oil recovery rather than hydrodynamics. Studying the aggregation of oil drops under different salinity conditions reveals the existence of optimal salinity conditions to maximize oil recovery.
