Analisis Numerik untuk Persoalan Water Flooding dengan Menggunakan Metode Volume Hingga

Abstract

Waterflooding simulation is usually done using Buckley-Leverett (BL) equation, which is the transport equation on dynamic fluid that describe two phase flow immiscible in porous media. In this case, we focus on nonequilibrium effect in the relative permeability with neglible capillary pressure, described by Barenblatt model, which includes both nonequilibrium capillary pressure and relative permeability. In this case, flux fluid of each phase on BL equation does not only depend on the current saturation (actual saturation) but also on the so called effective saturation. This paper is a review of what has been done by Juanes. However, the numerical discretization employs vertex centered finite volume for conservation laws (partial differential equation) and evolution relation (ordinary differential equation).
