POWERS, Saudi Aramco's first parallel reservoir simulator, has been used to simulate the production/injection history (1970 - 1996) of the complex Berri-Hadriya reservoir. The reservoir description was taken from a large window of the most recent Berri geostatistical model (StrataModel). The window contains the entire oil reservoir and a significant portion of the surrounding aquifer. The simulation model has 74 layers, 250-meter spacing, and 1.2 million cells. It was run on Saudi Aramco's 32-processor, massively parallel CM-5E computer.
The first history run yielded very encouraging results for matching water production rates and producing well pressures. Total execution time for the 26-year history was three CM-5E hours.
The presentation will discuss steps involved in history matching of geological models, together with the advantages of using such models; the environment for constructing/analyzing mega-cell simulation models; computational performance which can be expected; highlights of the POWERS development effort; and the Berri team's experience during the project.
