    Abstract

    An updating strategy is designed to iteratively close the loop among fluid-flow simulation predictions and measured production history, predicted and observed 4D seismic data, and finally predicted and inverted impedance/impedance changes. The central ingredient in this scheme is the inversion to elastic property changes from the seismic in an engineering-consistent manner. The geometry, volumetrics, and transmissibility multipliers for the reservoir model are updated in three successive stages, and success is monitored by a comparison between the seismic and fluid-flow domains. The workflow is implemented on a West African field, where reservoir model improvements are obtained in combination with a consistency among model, impedance, and seismic domains.
