SEISMIC GEOMORPHOLOGY - APPLICATION OF VOLUMETRIC DATA SCULPTING TECHNIQUES

Data sculpting is the extraction of a specific volumetric subset of interest within a volume of data. The main benefit of volumetric data sculpting is the ability to isolate paleomorphic features that are, in many cases, virtually undetected when interpretation is performed using typical exploration workflows.

Ancient stratigraphic features are sometimes undetected during the normal course of structural interpretation in the energy industry. Only recently has the emphasis, between structural and stratigraphic interpretation of seismic data, become more balanced in emphasis, during the exploration for new hydrocarbon resources. The evaluation of these salient paleo-stratigraphic features within 3D seismic datasets has proven to be vital in the final evaluation of prospective regions.

There are a variety of methods to isolate a geologic feature of interest using data sculpting. The application of the following volumetric data sculpting techniques are detailed and examined, with accompanying images of the final results. The techniques include: Key Horizon Bounded; Fault Sculpting; Stratigraphic Keyed; Attribute Keyed techniques. Horizon Bounded and Stratigraphic Keyed sculpting, will be the primary sculpting tools employed in this digital poster.
