Salt tectonics may be “an outlier in this country’s university training in structural geology,” but geologists entering the petroleum industry will almost certainly find themselves dealing with the topic, explained Mark G. Rowan of Rowan Consulting in Boulder, Colo. A growing understanding of how they form – especially since the 1980s – has been helpful in increasing their importance to exploration and production. Rowan discussed “Salt Diapirs – What Are They, How Do They Form and What is Their Role in Hydrocarbon Exploration?” at the recent Visiting Geoscientist Program Super Session organized by AAPG and the AAPG Foundation.

Management with the Dynamic Group of Houston are convinced after four years of study that they have identified significant new play potential deep on the west Louisiana shelf, a province largely regarded by industry as mature for exploration. “Most of our industry thinks the U.S. shelf is in late life, and the only remaining opportunities are for low-risk, low volume exploitation targets,” said Rob Pascoe, managing director and chief geologist. “We believe that may not be the whole story. Our studies describe a large-scale new play, with the potential to be liquids rich and high value.” He said new technology and geological insights are the key.

During the 1980s, early prospecting in deepwater margins was the simple extension of prolific updip producing basins that were charged. However, the migration of petroleum exploration and development into deepwater was fraught with challenges. For engineers and geologists, one of our biggest challenges was to overcome our collective lack of understanding about the geology of deepwater. We had to revisit everything we thought we knew, one paradigm shift after another.

In the early exploration days, petroleum geologists were required to take field trips to inspect, map and collect geological data in remote locations, sometimes inaccessible except by foot, horse, mule or boat. Geological publications and maps of these hard-to-reach regions were almost non-existent, and the first geologists had to start from scratch, without any of the geological information that present-day geologists take for granted. They faced hazardous and unsafe situations, including heavy rains, flash floods, rockfalls, landslides, sunstrokes, mosquito bites, venomous snakes and spiders, attacks from natives and wild animals, and endemic diseases such as malaria and yellow fever. Our story here is about a strange encounter with an enigmatic creature during a geological fieldwork expedition for oil exploration in western Venezuela, close to the Colombian border. The encounter was years later revealed to be one of the most notorious scientific frauds.

Understanding the role and influence of salt in the subsurface has been the key to many hydrocarbon discoveries and appraisals and more recently carbon & hydrogen capture and storage, and geothermal interests. Now, AAPG has a new Technical Interest Group, co-founded and co-chaired by Clara Abu (Ph.D Candidate Imperial College), Rachelle Kernen Ph.D., Leonardo Muniz Pichel Ph.D., Clara Rodriguez Ph.D., and Tim Shin, MSc. Welcome to an interview with Tim Shin, one of the co-founders.

Fault seal potential is an essential step in determining the potential for fluid migration and assessing risks during hydrocarbon exploration. Multiple assessment tools have been developed and focus on (1) lithological juxtaposition, of permeable and impermeable stratigraphic units, and (2) fault rock sealing, assuming that clay material gets smeared along a fault zone. Most of these tools rely heavily on well log data, whether it is collected and analyzed in 1-D or 3-D settings.

While the bulk of deepwater oil and gas discoveries in the northern Gulf of Mexico offshore areas lie within Cenozoic sandstones, Mesozoic siliciclastic reservoirs have been somewhat overlooked due to the depth and age of the reservoir section. That began to change with emergence of the Norphlet deepwater play, kicked off by discoveries in Mississippi Canyon and Desoto Canyon protraction blocks in 2010-13 by Shell and partners. The Norphlet reservoirs are aeolian (dryland) reservoirs located in modern abyssal water depths. However, the exploration potential of the younger Cretaceous section remains unknown, with just a handful of meaningful tests in deepwater areas.

The North Sea Rift Basin ranks as one of the world’s most famous and indefatigable super basin areas. Like a pugnacious prize fighter, it’s been counted out again and again, only to rebound and punch back into contention. While some explorers consider the North Sea province highly mature, and even late life, it continues to produce plenty of oil and gas. And discoveries.
