Evaluation of silicone fluids and resins as CO2 thickeners for enhanced oil recovery using a computational and experimental approach

"CO2 thickeners have the potential to be a game changer for enhanced oil recovery, carbon capture utilization and storage, and hydraulic fracturing. Thickener design is challenging due to polymers’ low solubility in supercritical CO2(scCO2) and the difficulty of substantially increasing the vis...
