Closing the loop using engineering-consistent 4D seismic inversion

    Research output: Contribution to conferencePaper

    Abstract

    An updating strategy is designed to iteratively close the loop (CtL) between the 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 computation of elastic property changes that are inverted from the seismic in an engineering-consistent (EC) manner. The geometry, volumetrics and transmissibility multipliers for the reservoir model are updated in three successive stages by sequential comparison between the seismic and fluid flow domains. The EC-CtL workflow is implemented on a West African field, where reservoir model improvements are obtained in combination with a consistency between model, impedance and seismic domains.
