INTERPRETATION OF GEOLOGIC DEPOSITIONAL SYSTEMS

A process that assists with the identification of potential hydrocarbon d eposits that includes performing a structural interpretation of a three-dime nsional seismic volume, transforming the three-dimensional seismic volume in to 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 Domai n Transformation is presented in Fig. 24a, interpreted horizons and faults u sed in the transformation are presented in Fig. 24b, and the Domain Transfor med stratal-slice volume is presented in Fig. 24c. The input seismic volume in Fig. 24a has deformations associated with syn- and post-depositional faul ting. The output Domain Transformed volume (Fig. 24c) is substantially free of deformations.
