The present study utilizes a microfluidic approach to investigate the effect of monoethanolamine (MEA) on increasing CO2 solubility in a light crude oil for low pressure immiscible enhanced oil recovery (EOR) operations. The CO2 microbubble area reduction over time was measured at varying MEA concentrations in oil to quantitatively estimate the effect of MEA on CO2 solubility, and as a result, its effect on gas-induced oil swelling and oil viscosity reduction.
