CO₂ Geostorage and Enhanced Oil Recovery: Challenges in Controlling Foam/Emulsion Generation and Propagation.

ABSTRACT: CO₂ injection in subterranean reservoirs for storage, oil recovery, or both is challenging because of its very high mobility. Using a CO₂ foam or emulsion is a way to remedy this problem by increasing CO₂'s apparent viscosity. However, the generation of the foam and its propagation in porous media present several issues that have to be overcome for this process to be economically realistic in practice. For example, it may take time, i.e., a number of pore volumes to be injected, before the foam is created. It is the objective of this Article to investigate these issues thoroughly and to identify the mechanisms underlying them by looking at the effects of various parameters. It is found that surfactant adsorption on the surface of the rock is an important fa
