Abstract:
Fluid flow modelling is usually based on "averaging strategies" which allow to reduce the number of unknowns in order to obtain accurate and efficient models. Classic fluid models like Navier-Stokes ones consider fluid particles which are usually large group of molecules and model their behavior using macroscopic quantities like densities, averaged velocities and so on. At a larger scale, porous media flow models use macroscopic cells containing "fluid and solid" information like porosity and permeability. Finally at the reservoir modelling scale, blocks of these macroscopic cells are used and upscaling procedures applied to produce large scale efficient models. This presentation will briefly introduce each of these "Upscaling" strategies. In order to check the validity of unstructured mesh Upscaling strategies, a single phase Control Volume Finite Element Method reservoir model will be presented. This model based on unstructured mesh calculations is then compared to a similar TPFA (Two Point Fluid Approximation) model to check its higher accuracy.
