Boundary Effects in the Successive Upscaling of Absolute Permeability
Abstract/Contents
- Abstract
- Reservoir descriptions generated by geostatistical techniques are usually done on a very fine scale and have far too many cells for any present day flow simulator to handle. The pressure-solver method is widely used in the petroleum industry to upscale such fine scale realizations into coarser ones with fewer cells. However, this method makes the assumption of constant pressure and no-flow boundary conditions. These assumptions can introduce errors in the upscaling process, resulting in an incorrect estimate of the effective permeability. This study determines the extent of these errors and outlines the conditions in which permeability upscaling by pressure-solver method works and others in which it fails. A range of geostatistical realizations have been studied and certain geometric and geostatistical parameters of these realizations have been highlighted which appear to have the greatest effect on the upscaling process.
