ABSTRACT

Recent advances in seismic technology, while spectacular in accomplishment, have been tied only rather loosely to the underlying geology. As one example, 3D surveys have primarily progressed imaging of structures, but have had more limited success with stratigraphic objectives, particularly for Consolidated formations. Such applications are, however, starting to emerge as, for example, use of the Amoco Coherence methods in delineating channels on time slice presentations. At the same time, improvements in geologic understanding and newer tools such as basin models remain poorly coupled to seismic technology. Seismic stratigraphy remains at present a qualitative method—almost an art.

Underlying all seismic methods, AVO, Tomography, Trace Inversions, VSP, etc., are fundamental ideas which are quite simple. The basic geological mechanisms by which sedimentary rocks are formed and rearranged are also in themselves readily understood. In bringing together sea level changes, sediment flows and tectonic processes with Fresnel Zones, and Wave theory we attain remarkable insights into the information potential of seismic data and a new view of the role of such data.

Interactive systems, 3D data, basin models, stratigraphic concepts, and other key technological directions, when effectively coordinated and integrated with one another, can offer the most definitive descriptions of the subsurface yet attainable for finding and defining hydrocarbon reservoirs. We consider here the early steps toward this technology “blending” by example rather than via theory. Such practical view suggests that even more exciting possibilities lie just ahead.
