CT scanning of core flooding experiments: Quantitative analysis of saturation without dopant

Core flooding experiments are used for testing enhanced oil recovery strategies (EOR) on a laboratory scale. In a typical core flooding experiment, the core plug contains oil, water and potential EOR agents. It is of importance to understand the multiphase flow of these liquid inside the porous rock formation. The combination of X‐ray CT scanning and image analysis has been used to study multiphase flow in porous media for a few decades. However, in low permeable reservoir rocks, the interpretation of multiphase flow experiments is still a challenge. Previous experiments have been conducted with the aid of dopants in oil or water phase, but this has been showed to be infeasible in chalk, as the dopants bind to the chalk.
