(54)Extraction of depositional systems


(57) A process that assists with the identification of potential hydrocarbon deposits that includes performing a structural interpretation of a three-dimensional seismic volume, transforming the three-dimensional seismic volume into a stratal-slice volume, performing a stratigraphic interpretation of the stratal-slice volume which includes the extracting of bounding surfaces and faults and transforming the stratal-slice volume into the spatial domain. As illustrated in Figs. 24a, b and c, an exemplary seismic volume before Domain Transformation is presented in Fig. 24a, interpreted horizons and faults used in the transformation are presented in Fig. 24b, and the Domain Transformed stratal-slice volume is presented in Fig. 24c. The input seismic volume in Fig. 24a has deformations associated with syn- and post-depositional faulting. The output Domain Transformed volume (Fig. 24c) is substantially free of deformations.
