Exploring the Deep Water Gulf of Mexico Petroleum Systems

John R. Dribus (Schlumberger Oil Field Services)spacer

To place the exploration geology of the deep water petroleum systems of the Gulf of Mexico into proper global context, this one day short course begins with a look at the transformation of global deep water exploration during the recent “lower and longer” oil price crash. Exploration activities have mostly switched emphasis from frontier exploration in untested or sparsely drilled basins to areas of known “commercial possible” discovery corridors, and to backyard exploration for deeper pools or for adjacent structures or stratigraphic traps within tieback range.

Then we will look at the three key northern Gulf of Mexico conventional deep water plays in the Jurassic (Norphlet Aeolian sandstone), Eocene/Paleocene/ Oligocene (Whopper, Wilcox, and Frio Formations), and subsalt Miocene/ Pliocene. Our focus will begin with a sequence stratigraphic perspective that looks at the sediments expected to be deposited in the slope and deep water basin plain during High Stands such as condensed section marine mudstones, Falling Stage including mud-rich mass transport deposits), and Low Stand depositional sequences such as basin floor fan and channel levee deposits.

Then we will discuss the critical factors in the deep water Gulf of Mexico Petroleum Systems beginning with forming the basin (global evolution and sources rocks), subsequent filling of the basin (carbonate and clastic reservoirs and seals), and migration through the overburden to the conventional reservoirs. This petroleum systems section of the class will conclude with a look at the deformation of the basin to create both structural and stratigraphic traps for hydrocarbon accumulation.

We will then turn to some interesting important auxiliary issues such as petrophysical considerations of pressure and diagenesis, and then review some aspects of the “Funny Looking Things” (FLT’s and DHI’s) that characterize many of the shallow prospects in the area, and then examine some of the challenges of drilling for the petroleum prize through the geohazards at the sea floor and around salt that are often in the way of the petroleum accumulations we seek.

Time permitting, we will conclude with a discussion of how we can utilize seismic data to help understand critical geologic risks of the turbidite play.

More about John R. Dribus:

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 16 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, Nova Scotia, the Northern and Southern Gulf of Mexico, Colombia, Equatorial South America from Trinidad/Tobago, Surinam, Guyana, 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. In 2017 he was recognized by the AAPG as an AAPG Heritage Geologist at the 100th Annual Convention in Houston.
