Abstract

High temperature and high-pressure microfluidics devices were built to screen surfactants for the CO2 foam behavior. The effect of chip geometry, surfactant type, concentration, shear thinning, and gas fractional flow effect on CO2 foam strength was conducted. Oil effect on foam was investigated by an oil fractional flow test. The steady-state foam results from the microfluidic device were used to estimate the STARS foam model parameters. The method we provide here is not only robust for fast surfactant screening and foam fluids transport phenomenon understanding, but also could provide STARS foam parameters for foam simulation purposes for evaluating the potential of the CO2 foam for a specific reservoir at the initial stage of experiment planning.
