COMBINED GEOSTATISTICAL AND DYNAMIC SIMULATIONS FOR DEVELOPING A RESERVOIR MANAGEMENT STRATEGY - A CASE-HISTORY

This case history describes a complete methodology from reservoir char acterization to reservoir management for a producing field. A two-stag e geostatistical approach was applied to distribute the reservoir hete rogeneity coherently over the field. Ten 3D facies distributions were simulated. In a second step, 10 porosity and permeability images were geostatistically simulated on the basis of facies distributions. After suitable upscaling, all 10 reservoir images were initialized in the d ynamic simulation model. The production history match was the discrimi nating criterion for the selection of the reservoir image to be used i n the forecast phase.
