Two sediment wave fields on the submarine slopes of the Canary Islands display wave heights up to 70 m and wavelengths up to 2.4 km. Wave sediments consist of fine-grained turbidites and pelagic/hemipelagic sediments. The sediment waves are formed beneath unconfined turbidity currents, and are similar to sediment waves found on channel-levee back-slopes.
Sediment wave morphology is resolvable on high-resolution seismic profiles. In areas lacking high-resolution seismic data, analysis of dipmeter readings may provide a useful tool for recognizing buried sequences of migrating waves. Thick sequences of sediment waves will impart a marked heterogeneity to a potential reservoir, leading to complications during reservoir production.
Figures & Tables
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.
