Deepwater Sedimentary Systems: Exploration and Production
Sandstones deposited in deep marine environments form important hydrocarbon reservoirs in many basins around the world. Interbedded mudstones can be important as source rocks, as well as acting as barriers, baffles and seals. Deepwater reservoirs are currently the principal target for oil and gas exploration, with over 1600 existing turbidite fields and plays. Driven by technological advances and much improved scientific understanding, the pace of exploration and discovery in this realm is fast accelerating. Keeping pace with these developments and with the new knowledge base is essential for all those involved in deepwater systems. What began as the turbidite reservoir has matured into the more varied deepwater play of the 21st century, including contourite and hybrid reservoirs. No company can afford to ignore these developments.
This course is designed to give the participant a state-of-the-art review and update, thereby providing an overall understanding of the complexity of the deep marine system. It will outline the processes and facies and how they evolve on the slope and in the open ocean; discuss how these facies build into distinctive architectural elements and how they can be recognized in the subsurface. The course also covers analysis and interpretation of seismic records, sea floor images, well logs (including borehole image logs), core materials, and outcrop characteristics of the component elements of deepwater reservoirs, emphasizing internal architecture as related to reservoir performance. Hands-on data packages from different deepwater plays around the world will be used to further illustrate their exploration, appraisal, development and reservoir management.
