Evolving Understanding of Salt Diapirs is Critical to Oil Exploration

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.

‘Significant New Play Potential' in West Louisiana Shelf

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.

The History of Deepwater Exploration, Part 2

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.

A Monkey's Photo, a Prankster Petroleum Geologist and a Fraudulent Anthropologist

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.

AAPG Salt Basins Technical Interest Group Interview - Tim Shin

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.

Assessing Fault Sealing Potential in 3-D Using Seismic Inversion Data

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.

Potential New Play Opening, Well Being Drilled in Mississippi Canyon

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.

North Sea Rift Basin Persists as a World Renowned Super Basin

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 By Rick Fritz

Always Pay Attention to the Really Big Things

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.

Instructors: Ricardo Pereira, GeoBioTec - Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa. Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: €190 - Local VAT applicable Limit: 20 Participants Includes: Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am Hotel Dom Pedro Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

How Orogens Could Collapse Forming Sedimentary Basins: The Case of the Betic-Rif Orogen

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

Salt versus Shales in Continental Margins and Orogens

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.
