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.

Explorer President’s Column

If you remember from my last column, this is a three-part series on my thoughts on science, membership and budget. I talked about budget last time … we are still working on it, so let’s talk science. The reason most professionals join AAPG is for access to science. That’s not just my opinion – it’s what members tell us. AAPG is very good about disseminating the work of our members and other professionals around the world. That’s our mission.

As discussed in part 1 of this article, when it comes to the attributes used in equation 1 for seismically determining shale capacity, it is difficult to make a manual choice for the cut off values. To alleviate such a problem, application of machine learning techniques could be useful and thus worth exploring.

It’s natural to think of super basins as highly developed, mature play areas. When a basin has already produced more than 5 billion barrels of oil equivalent, there’s an established history of exploration and production. The Santos Basin, especially the basin’s pre-salt play offshore Brazil, is one of the more notable exceptions to that idea. This super basin area is almost all about the future. “There is so much running room, so much remaining potential. We’re going to see new reservoirs developed, new plays developed,” said James Deckelman, vice president of investment and program assurance for ION Geophysical in Houston.

A new AAPG technical interest group is attracting international attention, and the founders hope to continue expanding the group’s influence. The Salt Basins TIG began in May 2020 as a way for geoscientists in industry and academia working on or interested in salt basins to connect, collaborate and share ideas, according to one of the co-founders, Rachelle Kernen of the AAPG Women’s Network.

Explorer Historical Highlights

There is something about colored pencils that we, as geologists, find impossible to resist. From geological maps to field sketches to interpreting seismic on those never-ending rolls of paper taped to the longest corridor wall we can find – what more could any geologist want? Our need for powerful software, paper and colored pencils reflects a fundamental problem in geology and especially exploration: how to manage, analyze and visualize the diversity and wealth of information required to solve exploration problems? Early geologists were faced with the same challenge 200 years ago. It was one of the first petroleum geologists, Thomas Sterry Hunt, who saw the value of paleogeography in exploration, and who, in 1873, first coined the term “paleogeography.”

Touchstone Exploration is the operator of the 184-square kilometer Ortoire Block onshore south eastern Trinidad. The block spans from the villages of Tableland in the west to Pierreville Mayaro in the east and to the very remote areas within the Guayaguayare forest to the south. Structurally, the block covers the greater part of the open east facing Ortoire Syncline which entails Late Miocene Lower Cruse to Pleistocene Mayaro Formation deltaic fill. These passive fordeep infill deposits sit conformably onto a southeastern-verging Early to Middle Miocene fold belt. As such throughout the breadth of the Ortoire Block there are numerous tear fault dissected west-southwest to east-northeast trending anticlines.
