Welcome to an interview with Garish Saigal, Statoil, a convenor in the upcoming Geosciences Technology Workshop on Deepwater Reservoirs in the Gulf of Mexico GTW (January 18-19, 2011 – Houston).

a) What is your name and your affiliation?
My name is Girish Saigal and I work for Statoil, Gulf Of Mexico, Houston.

b) What is your role in deepwater E&P?
Currently I am working as a Lead Geologist in Field Development department. I work in an integrated environment to characterize reservoir types in deepwater GOM. The focus is on understanding reservoir complexities and identifying upsides and risks in Miocene as well as Paleogene fields.

c) What do you think is important for all E&P professionals to know about deepwater geology, geophysics, and/or engineering?
Regarding deep water GOM reservoirs, one must appreciate the gaps in our understanding of the deep water depositional process, salt-sediment interaction, and identifying degree of compartmentalization in deeply buried (>25000 ft), subsalt deepwater GOM reservoirs.

Seismic imaging in subsalt environment is an enormous challenge for all E&P professionals, therefore, understanding the limitations of technology is important to avoid over-interpretations.  Complex and frequently variable geology in relatively rapidly buried GOM basin poses several drilling and development challenges.

d) How does taking an interdisciplinary approach help in developing an understanding of deepwater operations?
Due to high cost and risks involved in deepwater operations it is important to work in an interdisciplinary environment where each discipline is represented by proactive technical experts. Understanding the risks and uncertainties of each discipline is critical to ensure optimal execution of deepwater projects.

e) Why are you excited about the upcoming AAPG Deepwater Reservoirs in the Gulf of Mexico workshop, and how is it a special event? What differentiates it from other events?
I participated in the last workshop and found it to be relatively informal and open in terms of interaction between audience and speakers. A workshop type environment is probably more educational as most participants feel free to raise points that are either not covered by the speaker or considered relevant; but turns out to be valuable. �

This two-day workshop is targeted at geoscientists and reservoir engineers who are actively involved in deepwater exploration, development, and technical studies. The goals of the Deepwater GTW include providing a forum that showcases integrated studies of deepwater reservoirs, affording ample opportunity for dialog and lively group discussions, and facilitating interdisciplinary innovation in these challenging environments. Each session will include an IPOD discussion (in-depth discussion on issues, problems, opportunities, and directions).

We are planning a full day of talks and discussions focused on pre-Tertiary (Paleogene) exploration and development, as well as a full day on the Miocene and Pliocene. Most presenters hail from either the asset teams or research teams of some of the most innovative deepwater operators, including Shell, Chevron, Anadarko, Statoil, Noble, BP, Nexen, Ecopetrol, and Petrobras. Academia and top service providers will also be well represented, both as presenters, and adding to the quality of the group discussions.

For informed, small-group discussions that focus on practical, relevant geosciences, there is nothing like an AAPG Geoscience Technology Workshop. We are very privileged for 2011 to have the Society of Petroleum Engineers (SPE) as a co-sponsor of the Deepwater GTW!
