A good understanding of the internal geometry of a reservoir is necessary for making realistic oil recovery forecasts. In answer to this need, software has been developed to generate 3D lithological images of a reservoir by using a geostatistical approach. Based on previous images, a petrophysical description is then obtained on a geologic mesh scale. And to perform flow simulation, petrophysical parameters must then be scaled up to reservoir mesh scale. This paper shows an application of the complete procedure of processing from geostatistical imaging to fluid flow modeling.
