Geological Constraints in Model-based Seismic Inversion

Geologically Constrained Inversion is an extension to the Shell proprietary Promise stochastic inversion engine that takes lateral continuity and well constraints into account. The new algorithm produces an ensemble of reservoir-size (as opposed to single-position) models that match the seismic data, the geological constraints and the well data. The results are geologically more realistic than those of the original single-position inversion. The algorithm is parallelized so that it can be applied to real-world size datasets.
