Prasad et al. (2023): A review of the supercritical CO2 fluid applications for improved oil and gas production and associated carbon storage

Siddhant Kumar Prasad, Jitendra S. Sangwai, Hun-Soo Byun IN: Journal of CO2 Utilization 72, 102479, https://doi.org/10.1016/j.jcou.2023.102479

Supercritical fluids find use in various areas in oil and gas production operations due to their unique properties. Supercritical CO₂ (sc-CO₂) with its reduced viscosity, increased diffusivity, and liquid like density, is attractive for enhanced hydrocarbon recovery, shale gas fracturing and drilling (especially in underbalanced condition). However, many technical, financial and policy challenges need to be overcome to realize the success of the CO₂-EOR/storage project and achieve carbon neutrality. This review paper discusses such challenges, the current mitigation practice, gaps and future direction of research.
