Extraction of depositional systems

Abstract

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. 24 a, b and c , an exemplary seismic volume before Domain Transformation is presented in FIG. 24 a , interpreted horizons and faults used in the transformation are presented in FIG. 24 b , and the Domain Transformed stratal-slice volume is presented in FIG. 24 c . The input seismic volume in FIG. 24 a has deformations associated with syn- and post-depositional faulting. The output Domain Transformed volume (FIG. 24 c ) is substantially free of deformations.

1 . A method for assisting with the identifying structure within a volume comprising:
 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;   transforming the stratal-slice volume into the spacial domain; and   transforming the bounding surfaces into the spatial domain.
