Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 612-637, December 2025.
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)

Oil Displacement in Calcite-Coated Microfluidic Chips via Waterflooding at Elevated Temperatures and Long Times

Micromachines, 2022
In microfluidic studies of improved oil recovery, mostly pore networks with uniform depth and surface chemistry are used. To better mimic the multiple porosity length scales and surface heterogeneity of carbonate reservoirs, we coated a 2.5D glass ...

Polymer Flooding Dynamics in Enhanced Oil Recovery: A Pore‐Scale Study of the Influence of Shear‐Thinning Rheology on Flow Dynamics and Recovery Efficiency

Journal of Applied Polymer Science, Volume 142, Issue 29, August 5, 2025.
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.

Pore‐Scale Study of Non‐Clogging Accumulation Effects on Microgel Particle Transport and Multiphase Displacements in Porous Media

Water Resources Research, Volume 61, Issue 6, June 2025.
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

Modeling Approach to Mechanical Gas Dewatering of Filter Cakes With Non‐Uniform Cake Height

Chemical Engineering &Technology, Volume 48, Issue 1, January 2025.
This study explores how non‐uniform cake heights affect gas dewatering of filter cakes. By applying conservation laws and pre‐measured capillary pressure and relative permeability functions, predictions align well with experimental data. Abstract Gas dewatering of filter cakes with non‐uniform cake height is investigated.
