Experimental and Numerical Study on Optimizing CO₂ Foam-Assisted Gas Channeling Control in Tight Reservoirs: Geological Influences.

ABSTRACT: Under the goal of carbon neutrality, CO₂ foam flooding combined with the sequestration offers multibenefits for the development of low-permeability and tight oil reservoirs. However, its effectiveness is often hindered by severe gas channeling caused by foam instability and complex geological conditions. This study investigates the foam performance of two foaming agents inside tight porous media via core flooding tests, followed by reservoir-scale optimization studies of foam injection strategies, which are subsequently performed to assess the effectiveness of foam-assisted gas channeling control under different geological scenarios. The results elucidate the impact mechanisms of geological heterogeneity on the CO₂ foam performance and provide theoretical and technica
