TWO-PHASE FLUID FLOW CALCULATION METHODOLOGY FOR POROUS MEDIA AT DIFFERENT PRISMATIC GRID TYPES
The article describes the two-phase fluid filtration calculation for non-mixing fluids based on the Black-oil model with an application of structured and unstructured prismatic grids. Equations solution is conducted through a fully implicit finite volume method. The described approach is tested on the SPE8 algorithm. Quantitative and quality parameters correlate with the commercial software package Rubis (Kappa Engineering).
