The Effect of the Geological Model on History Matching in the Lower Cretaceous Wassenaar Field, NL

L-24 THE EFFECT OF THE GEOLOGICAL MODEL ON HISTORY MATCHING IN THE LOWER CRETACEOUS WASSENAAR FIELD NL Abstract 1 The Wassenaar Field started up production in 1956 and was closed in in 1989. It provides a excellent real case for oil field modelling and “what if” scenarios for the testing of models based on modern technology. This paper focusses on the construction of a reservoir model and the subsequent history matching. The production history of all 60 wells has been analysed. The existing geological models were modernised. However the latest geological models are still insufficient to explain the discrepancies in
