This course is based on the systematic, comparative interpretation of modern, long offset, regional seismic profiles with time and depth migration and several suites of selected 3D data in the deep-water realm from around the world.
Duration
Two days
Intended Audience
Intermediate Level
Prerequisites (Knowledge/Experience/Education Required)
Basic understanding of geology and seismic methods.
Course Outline
Topics include:
- Continental Margins: Slope, Rise and Basin; Deepwater Depositional Environments; evolution of sedimentary environments through plate tectonic interactions and sea level change; basic seismic stratigraphic interpretation principles as applied in deep water
- Salt Basins: Gulf of Mexico (GoM), East Brazil, West Africa, North Sea, Mediterranean, Red Sea, Caspian Sea
- Salt Tectonics: Allochtonous Salt vs Autochthonous Salt vs Pre Salt – Worldwide Comparative Examples
- Basins Without Salt: Atlantic Equatorial Margin, South Atlantic Margins; East Africa, Asia and Southeast Asia; Far East Archipelago, Northwest Australia; New Zealand
- Deepwater Petroleum Systems: Discussion of source rocks, migration paths, reservoirs and seals; pressure regimes (optional module)
- Seismic signatures of deep-water reservoirs; Role of amplitude & attribute analysis
- Future Trends in Deep Water reservoir exploration, characterization and production
Learner Outcomes
