Jahrul M Alam, Mohammad Jalal Ahammad · arXiv (Cornell University) · 2014
Understanding miscible flow of CO$_2$ and oil in a porous media is an important topic in the field of petroleum engineering. In this article, we present an upscaling methodology for displacing oil by CO$_2$, and study the statistical mechanical theory to develop a subgrid scale model for the effect of CO$_2$-oil dissolution on the overall skin friction and pressure drag experienced by the porous media. We present a multiscale computational methodology for a near optimal calcuation of the velocity and pressure. We study the field scale sweep efficiency using a streamline based Lagrangian scheme. The simulation results show a good agreement with asymptotic analysis results.
