Building geologic models of turbidite reservoirs for simulation and development planning using only subsurface data suffers from either discontinuous information or information that is displayed at too large a scale of resolution to detect variations in significant geologic properties. Large, continuous outcrops help constrain characterization of reservoirs by providing quantitative lateral and vertical attributes of strata and their bounding surfaces. Besides the traditional tools for examining outcrops, newer techniques include photo imaging, behind-outcrop logging/coring/seismic, gamma-ray/velocity logging, permeability profiling, and ground-penetrating radar. When used in combination, reliable, quantitative characterizations of tur-bidite outcrops can be developed. Future research should focus on full 3-D quantification of outcrops.

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.
