Co-visualization - A Visual Approach to Linking 4D Seismic Response to Reservoir Simulation

Building a geomodel is a complex task which tries to reconcile what seems to be two contradictory<br>objectives: one is to be the most realistic for imitating as best as possible the sedimentology and the<br>complexity of heterogeneities, the other is to be the simplest representation of features that have a real<br>impact on the field production. During the long process of construction, key choices are done like<br>simplification of the fault pattern or of the sedimentary bodies. Therefore, when the static geomodel is<br>finished, before entering in the reservoir history matching phase, it is important to replace the<br>geomodel back on the seismic data in order to check that, beyond the numerous choices that were<br>done, the generated grid is still “compatible” with seismic attributes.
