This is an in-depth course which not only provides the background of process sedimentology required to understand deepwater systems but also teaches recognition of sediment gravity flows on sub-surface datasets. The instructor will present examples of deepwater depositional systems from world-famous outcrops such as the Ross Sandstone, the Ecca Group of South Africa, and the Ainsa system of the Spanish Pyrenees and others. The course slides are richly illustrated with seismic, well-log, and core data from basins across the globe.
Morning sessions will be devoted to lectures and afternoon sessions will be devoted to exercises where participants will learn the latest techniques in interpreting process sedimentology, and identification of architectural elements such as channels and lobes in core, conventional well-logs, borehole image logs and seismic data.
The instructor will bring a teaching collection of seismic lines, well-logs, borehole images, and core images with for participants to work on during exercises. These are from the North Sea, Offshore West and East Africa, Offshore Indus, the Barents Sea, Offshore Mid-Norway, and the Gulf of Mexico.
Who Should Attend
Geologists, Geophysicists, Petrophysicists, Engineers and Managers who wish to develop a better understanding of the factors that control reservoir distribution, quality, connectivity and compartmentalization in deepwater systems. The course assumes no prior knowledge and will provide participants with a solid foundation that they can translate into their daily tasks during exploration and development.
At the end of the course participants will have a greater understanding of and have developed the following key attributes:
- Solid understanding of deepwater processes and the deposits they produce
- Identification of sedimentary structures using borehole image logs and interpreting depositional environments in FMI logs
- Seismic expression of lobes, fans, channelized lobes and mass transport complexes
- How to approach deepwater reservoirs from exploration to development, systematic approach in seismic interpretation of deepwater sedimentary successions
- Creating geomodels: creation of facies logs, deriving geometric data such as channel thickness and width, sinuosity, and choosing the best algorithm for modeling deepwater architectural elements
- How to identify deepwater processes by looking at core data
Key Course Highlights

- Deepwater lobe beds, lobe elements, lobes, lobe complexes and fans
- fluid gravity vs sediment gravity flows, hypopycnites, hyperpycnites, debrites, contourites (bottom-current deposits), turbidites, hybrid beds, linked debrites, and slurry flows
