Interpreting Turbidite Systems with 2-D and 3-D Seismic Data: An Overview
A significant portion of the geologic community’s understanding of tur-bidite systems is derived from the interpretation of 2-D and 3-D seismic data. The images generated from 3-D seismic data, in particular, have caused the re-examination and reinterpretation of deep-water sedimentary processes. In the future, the integration of 3-D seismic data with other data sets and technologies will continue to increase our understanding these systems, and specifically for improved reservoir management in turbidite reservoirs. Some of the new areas of investigation will include: increased study of modern fans and intraslope turbidite systems by integrating multiple data sets (deep cores, sidscan images) with 3-D data; the use of 4-D seismic and reservoir monitoring; repeat 3-D seismic surveys integrated with reservoir simulation; time lapse, multicomponent (4-D, 3-D); artificial intelligence, viz, neutral networks for more accurate lithologic prediction; and the use of large-scale visualization rooms in enhancing interpretation.

This Memoir covers one of the most important and active exploration reservoirs being pursued by geoscientists worldwide: fine-grained turbidite systems. 28 chapters show the results of an intense research effort in the 1990s that resulted from the discovery of large hydrocarbon accumulations in fine-grained turbidite systems in Brazil, the Gulf of Mexico, West Africa, and the North Sea. Industry and academia have joined together in this publication and the result is a unique opportunity to study these turbidite systems from the outcrop to the modeling; through the interpretation with 2-D and 3-D seismic data; to case histories and analog studies from Arkansas and Oklahoma, South and West Africa, Gulf of Mexico, west Texas, and New Zealand.
