Workshop in Integrated Geological and Geophysical Interpretation of Deep Marine Deposits
Next Event
The course is aimed at exploration, development, and operations-level interpreters working in areas dominated by deepwater depositional systems. Through a combination of lectures and case studies, participants are exposed to many aspects of seismic stratigraphic interpretation, with an emphasis on predicting, mapping, and quantifying deepwater reservoirs.

Schedule
Duration and Training Method
A classroom course comprising a mixture of lectures, workshops, exercises, and case studies from carbonate and siliciclastic settings around the world.
Course Overview
Learning Outcomes
Participants will learn to:
- Assess, map, and quantify deepwater depositional systems.
- Evaluate seismic facies to develop depositional models and predict reservoir presence, distribution, and quality.
- Construct seismic interpretations by integrating analogues, models, and well data.
- Analyze reflection terminations and configurations on seismic data.
- Assess the implications of interpretations on lithology, net-to-gross ratio, and reservoir properties.
- Evaluate the geomorphology of deepwater depositional systems using quantitative seismic geomorphologic techniques.
Course Content
The lecture content provides a summary of the fundamentals of deep marine systems. The principal goal of the course is to equip subsurface interpreters with a methodology and hands-on experience in seismic stratigraphic interpretation of deepwater depositional systems. The course is designed to foster instructive discussions among experienced professionals, moderated and guided by the tutor. Participants are encouraged to bring examples of their own data for discussion.

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.
