We use lithoseismic classification on geostatistical inverted seismic data to access multiple realizations of lithofacies attribute cubes. We study the variability of predicted lithofacies values to compute in 3D a confidence attribute cube. This confidence cube helps the interpreter to evaluate the robustness of a predicted lithofacies value at any point for further reservoir model building. As a result, a case study on a Gulf of Guinea dataset led to a probabilistic characterization of the connectivity between producing intervals. © 2011 Society of Exploration Geophysicists.
