Abstract

Geological model is normally built with huge number of grid cells (106 – 107 cells) in order to model in details the geological heterogeneity of an oil field. Although increasingly developed nowadays, modern computers would be faced with substantial problems size in reservoir simulation. Upscaling the geological model before running numerical simulation, therefore, is greatly important to reduce the simulation model size while retaining the geological heterogeneity of the oil field. This paper presents an overview of fundamental background on upscaling methods and reports research results in applying various upscaling methods as well as suggests the most suitable methods for Te giac trang oilfield.
