Summary
The course is aimed at seismic interpreters working in areas dominated by deepwater depositional systems. Through a combination of lectures and case studies, the participants are exposed to many aspects of seismic stratigraphic interpretation, with emphasis on predicting, mapping and quantifying deepwater reservoirs.
Duration and Training Method
A three-day classroom course comprised of a mixture of lectures, workshop, exercises and case studies.
Participants will learn to:
- Assess, map, and quantify deepwater depositional systems.
- Evaluate seismic facies to create a depositional model and predict reservoir presence, distribution, and quality.
- Construct seismic interpretations by integrating analogues, models and wells.
- Evaluate reflection terminations and configurations on seismic data.
- Assess implications of interpretations on lithology, net-to-gross, and reservoir properties.
- Evaluate the geomorphology of deepwater depositional systems using quantitative seismic geomorphologic techniques.
The lecture content provides a summary of the fundamentals of deep marine systems. The principal goal of the course is to provide subsurface interpreters with a methodology and hands-on experience in seismic stratigraphic interpretation of deepwater depositional systems. The course is intended to generate instructive discussion among experienced professionals, moderated and guided by the tutor. Participants are encouraged to bring examples of their own data to discuss.

Background
My technical expertise is in clastic sedimentology, sequence stratigraphy, and seismic geomorphology. I specialize in the study of land margins and the processes, deposits, and fluid systems that characterize them. This interest extends to systems on other planets, as well as on Earth. I have extensive experience in physical modeling of clastic processes and a strong interest in predictive models of complex geomorphic response to extrinsic and intrinsic changes.
In addition, I have research interests in gas hydrates, shale tectonics, and the biotic and fluid systems of deep-ocean mud volcanoes. My industry experience includes integrated study of petroleum systems, exploration prospect development and operations, and regional hydrocarbon prospect evaluation. I am well versed in the integration of biostratigraphic, oxygen isotopic, geochemical, seismic, and well log and production data for subregional and regional sequence stratigraphic and basin analysis.
