Seismic Interpretation in Deep Water Basins

Roberto Fainstein

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.


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

To understand:

  • How deep-water salt basins compare with deep-water basins without salt
  • Regional differences in Salt Tectonics
  • Challenges of Pre Salt Interpretation
  • Methods to Interpret post-salt, sub-salt and pre-salt stratigraphy and structure
  • Role of fracture zones, basement features and igneous intrusives
  • Value of Regional Interpretations of 2D lines and merged 3D volumes
  • How to recognize seismic signatures of deep-water reservoirs – turbidities, fans, channels, and carbonates
