Modeling and CT-Scan Study of Foams for Acid Diversion

摘要

In this paper we present a 1D and 2D analysis of foam development in porous media based upon a new stochastic bubble population foam model and provide a detailed experimental validation. We present systematic experiments consisting of the co-injection of N2 gas and surfactant solution in homogenous sandstone cores, varying the liquid and gas injection rates. During the experiments X-ray computed tomography (CT) scans were used to map locally the fluid saturations with high spatial and temporal resolution.
