Abstract
Engineering-consistent (EC) concept is built into a “coupled” 4D inversion workflow to represent the reservoir changes. The inversion, with geology and reservoir engineering constraints, is performed on a consistent reservoir grid. The result takes time shift into consideration and shows less non-uniqueness according to the production activities. We applied the method to a West Africa field and updated the reservoir model by improving its dynamic behavior and the consequent match between the synthetic and observed 4D seismic data.
