Foam mobility in heterogeneous porous media
WebApr 19, 1998 · Laboratory experiments have shown that some surfactants generate "smart" foam that selectively reduces mobility of CO2 by a greater fraction in lighter than in lower permeability cores. The occurrence of such an exciting property in foam displacement and its application to improving oil recovery in heterogeneous porous media are discussed … WebAug 13, 2024 · Summary. This paper advances the understanding of foam transport in heterogeneous porous media for enhanced oil recovery (EOR). Specifically, we investigate the dependence of methane foam rheology on the rock permeability at the laboratory scale and then extend the observations to the field scale with foam modeling …

WebNov 11, 2024 · Preferential flow that leads to non-uniform displacement, especially in heterogeneous porous media, is usually unwelcome in most practical processes. We propose a self-adaptive preferential flow control mechanism by using dispersed polymers, which is supported strongly by experimental and numerical evidence. WebAug 1, 2007 · We report an experimental study of the motion of foam in granular porous media using X-ray Computed Tomography.The experiments consist of the co-injection of nitrogen and a surfactant solution in natural sandstone to generate foam. When foam reaches the steady-state flow regime, we replace a fraction of nitrogen by a tracer gas …
