CO2-WAG Enhances Oil Recovery and Controls Gas Channeling in Low-Permeability Reverse-Rhythm Carbonates
This study aims to reveal the oil displacement mechanisms and gas channeling behavior of continuous CO2 and CO2-water alternating gas (CO2-WAG) in low-permeability, reverse-rhythm carbonate reservoirs, thus providing a theoretical basis for optimizing development strategies. We designed reverse-rhythm physical core m...
