This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Abstract Cyclic injection of immiscible fluids in porous media is a key process in applications such as carbon geosequestration and underground hydrogen storage, where understanding and predicting the residual trapping efficiency are critical. This study develops a modified invasion percolation algorithm incorporating a pore coupling coefficient to ...

Based on the theory of porous media elasticity and the mechanisms of hydraulic‐mechanical coupling, a fully coupled mathematical model for porous media deformation and fluid flow was established, incorporating a square inverted nine‐spot well pattern with artificial fractures. The finite element method was employed for numerical solution, and the model′

Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)

This study explores how polymer behavior affects oil recovery in porous rocks. It shows that shear‐thinning polymers become less effective at high flow rates, reducing oil displacement efficiency. The findings highlight the need to optimize polymer injection rates and formulations for better recovery.

Abstract Particle transport in subsurface porous media under multiphase flow conditions is widely concerned in many practical applications. Previous studies have focused on retention behaviors and interfacial effects, ignoring the unique role of pronounced rheological effect under dilute conditions. Here, we investigate how accumulation effect reshapes

Experimental Study on Hysteresis During Cyclic Injection in Hierarchical Porous Media
Abstract Cycle injection schemes are often encountered in underground hydrogen storage (UHS), and the involved hysteresis directly impacts storage and extraction efficiency. The geological formation generally has hierarchical features containing multiple‐level pore sizes.
