LGS Luncheon – March 2017


Title: Recent Significant Global Deepwater Discoveries and the Look Forward for Deep Water Exploration.

John R. Dribus

This talk begins by examining some of the key factors that are negatively impacting global exploration activities today. Then, several areas that have received focused exploration attention in 2015-2016 such as Brazil and Angola Presalt, the Gulf of Mexico Lower Tertiary, Senegal and western Africa basin margin turbidites, and others are discussed, including recent key global deep water discoveries. Exploration challenges of the Brazilian and Angolan presalt plays are examined, and successes in the Gulf of Mexico, Newfoundland, Senegal and other areas are reviewed. Then the talk looks to the future by reviewing important deep water exploration wells that were scheduled to be drilled in 2016, and their potential impact. The talk then closes by looking at a few other interesting areas around the globe that are very likely to receive exploration attention beyond 2016 and drilling within the next two to three years.




John Dribus is the Global Geosciences Advisor for Schlumberger Oil Field Services.  He is a Reservoir Geologist with over 40 years’ experience, and has worked all aspects of petroleum exploration, exploitation, and production geology. He worked five years as a uranium field geologist, and then 20 years for Mobil Oil Corporation as a petroleum geologist, including 14 years working the deep water Gulf of Mexico and subsalt province, and managing their Gulf of Mexico Geologic Risk Analysis team.

He has worked the past 15 years for Schlumberger as Northern Gulf of Mexico Data and Consulting Services Manager, and as the Global Geologic Advisor for exploration and deep water projects. He has worked deep water basins in Western Greenland, Newfoundland, the Northern and Southern Gulf of Mexico (including Mesozoic carbonates of onshore Mexico), Colombia, Equatorial South America from Trinidad/Tobago, Surinam, French Guiana, Ceara and Portiguar Basins in Brazil, the Brazil pre-salt play in Santos and Campos Basins, the Malvinas/Falkland Island Basins, South Africa, Angola presalt in Kwanza and Benguela Basins, Gabon clastic presalt, Ghana Jubilee turbidite play, Liberia and Sierra Leon  turbidites,  Mauritania/Senegal turbidites, the Black Sea, and the Red Sea.

His primary focus has been on understanding the petroleum systems characteristics of basin fan floor and channelized turbidites, pre-salt and subsalt carbonates and carbonate diagenesis, and other clastic reservoirs of the Atlantic margin basin. His expertise is in exploration, clastic and carbonate sedimentology and sequence stratigraphy, petroleum systems analysis, global deep water analogs, exploring in salt basins, sea floor and salt-related hazards, and geological risk analysis.

He is the former Chairman of the Advisory Broad of the American Petroleum Institute (API) Delta Chapter, serves on the Imperial Barrel Award Committee of the American Association of Petroleum Geologists (AAPG), and is a member of the AAPG (30 years), New Orleans Geological Society (NOGS), Houston Geological Society (HGS), and the Society of Petroleum Engineers (SPE), and European Association of Geoscientists and Engineers (EAGE).

In 2013, he was recognized by the Society of Petroleum Engineers with the Eastern North America Region Reservoir Description and Dynamics Award. In 2014, he was an invited speaker at the AAPG Discovery Thinking Forum and Playmaker Forum, and received the Meritorious Service Award from the American Petroleum Institute (API) Delta Section.
