Abstract
Different demands for reservoir engineering and geomechanical meshes have led to a new upscaling technique. This technique uses the well known Backus averaging method for material parameters, with a new method to also upscale pressure and temperature changes. It assumes pressures and temperatures are not uniform over the formation or that formation contains (impermeable) non-pay zones. The method has been tested successfully in geomechanical upscaling of meshes and is intended to be used to upscale reservoir engineering meshes and results as well, allowing direct coupling of results.
