Title: Stratigraphy from Three-Dimensional Seismic Data: ABSTRACT

Author(s): Alistair R. Brown

Article Type: Meeting abstract


The interpretive benefits of three-dimensional seismic data are enormous because of the considerable improvements in subsurface resolution. In addition to the benefits for structural definition, the horizontal section can provide a display of ancient deposition and stratigraphy similar to that of modern deposition seen from an airplane window. On horizontal sections and horizon slices, we can observe directly the shape of offshore bars, meandering channels, delta-front channels, and crevasse splays, and also the extent of bed truncations at unconformity surfaces. Many of these features may be hydrocarbon reservoirs, and color display of modern well-processed three-dimensional seismic data considerably aids reservoir identification. Proper interactive use of three-dimensio al data during appraisal and development permits the determination of downdip limits and the mapping of reservoir quality, especially porosity and net-pay thickness.
