Predicting Lithofacies Using Prestack Seismic Data

Capture reservoir heterogeneities and detail normally not feasible with standard reservoir characterization workflows. A 3D reservoir property model is fully described by the principle subsurface rock types and their accurate spatial distribution. This demonstration significantly expands the traditional uses of pre-stack data for seismic characterization through the use of classification procedures for predicting lithofacies away from the wellbore and for assessing uncertainty for each rock type. This innovation enables workflows that capture reservoir heterogeneities and detail normally not feasible with standard reservoir characterization workflows.
