The oxidation of heavy oil (HOO) during In-situ combustion (ISC) within the porous media of reservoir rock matrix is a critical process. Although previous research has individually investigated the catalytic capabilities of clay minerals (e.g., kaolinite) and carbonate minerals (e.g., dolomite) in HOO, their combined influence remains unexplored.
