Abstract

We present a seismic history matching workflow where 4D seismic data is assimilated in the pressure and saturation domain, using the results of a previously computed Bayesian 4D seismic inversion. The inversion provides an estimation to the changes in pressure and saturation and also their related uncertainties. This uncertainty estimation is assimilated into the history matching workflow in a weighting approach, by penalizing the seismic inversion maps with respect to the Bayesian inversion uncertainties. We show that the proposed penalization method leads to a focused assimilation of the trustworthy seismic information, which may prove crucial when assimilating seismic data in the pressure and saturation domain. The workflow is applied to a real data case to assess and update global reservoir connectivity in a North Sea reservoir.
