Abstract

Aqueous foam is a two-phase system consisting of a continuous liquid phase and a dispersed gas phase. Foams are widely used in a variety of industrial operations, such as the enhanced recovery of hydrocarbons. Because of their unique properties, they can solve a variety of reservoir heterogeneity problems, including early gas breakthrough, channeling, and even viscous fingering. A variety of phenomena affect the stability of foams during flow, for example, the drainage process, gas diffusion, and bubble coalescence. In this research, we used the level-set method to simulate foam stability in various aspects, such as factors affecting foam drainage and coalescence phenomena. According to the simulation results, the foam's lifetime is greatly impacted by the phenomena of drainage and coalescence. Moreover, its stability is strongly influenced by salt as well as the type of gas used to generate it
