Reservoir characterization using ensemble smoother with selected measurement data for each well

초록

In this paper, the selective use of measurement data using Ensemble Smoother is suggested in order to improve its performances by reducing the possibility of misuse of observed data. Key idea is that observed data are selected out on the basis of water breakthrough for better reservoir characterization. We use oil production rates before water breakthrough and water cut rates after water breakthrough for each well because ES cannot interpret the physical characteristic of water breakthrough properly. The consequence is that the proposed method gives us the best reservoir characterization of results with clear channel patterns and connectivity.
