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.
India is a land that is rich with geological wonder, but is also beset with social and environmental problems. A group of AAPG members is using their knowledge and love of geology to create opportunity and hope on the subcontinent.
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.
Some 257 people gathered at the beautiful new Hilton Hotel in Port Moresby, Papua New Guinea in the last week of February 2020 to attend the first AAPG/EAGE Papua New Guinea Petroleum Geoscience Conference and Exhibition. The theme for the conference was, “PNG’s Oil and Gas Industry Maturing Through Exploration Development and Production.”
Each year, AAPG's Petroleum Structure and Geomechanics Division recognizes what the membership considers the best recent and seminal publications in the field. This year's Best Seminal Publication award recognizes Tod Harding and Jim Lowell for their 1979 paper, 'Structural styles, their plate-tectonic habitats, and hydrocarbon traps in petroleum provinces,” published in the AAPG Bulletin 63. Division Chair Bob Krantz praised the work as 'truly foundational.'
AAPG and EAGE are proud to jointly present the first Geosciences conference in Papua New Guinea in two decades.
Endorsed by Department of Energy, PNG and supported by the PNG Chamber of Mines & SEAPEX, the conference will review the petroleum geology of Papua New Guinea in its tectonic setting as host to petroliferous marginal Phanerozoic basins on the northeast margin of the Australian continent.
AAPG and the Brazilian Association of Petroleum Geologists invite you to join us for GTW Brazil 2019: Solutions for Appraisal and Development of Onshore and Offshore Fields, a Geosciences Technology Workshop (GTW) to be held at the Hilton Rio de Janeiro in Copacabana on 13-14 June.
The workshop features a series of technical presentations, panels, roundtable discussions and networking opportunities with leaders and experts from Petrobras, Shell, Total, Enauta, and other local and international operators.
The continent of Africa has beguiled geologists for centuries. Its varied and beautiful landforms and geological features, its mineral and energy resources, its cultural heritage – it’s the birthplace of our species – all combine to form a rich experience of sights and sounds, aromas and flavors. Once you’ve been to Africa, you want to go back. And that’s why, after 10 years, we’re heading back to Africa next month – back to Cape Town, for the 2018 AAPG International Conference and Exhibition.
Geoscientists have a special obligation. We are the historians of Earth’s past, much as medical researchers have a responsibility regarding the understanding and honest communication of the functions of the human body and lawyers to understand and correctly interpret the law. Many of the tools we have established in our search for oil and gas, from plate tectonics to seismic stratigraphy, to study of paleoenvironments and paleontology, are being applied to understanding the geologic past in ways that document climate change.
Carlo Doglioni, professor of Earth Science at Sapienza University in Rome, is one of this year’s recipients of the Robert R. Berg Outstanding Research Award.
This workshop brings together experts from academia and industry from a range of disciplines to share experiences, new approaches, new data and new ways of integrating information that can help in reducing the uncertainties related to the exploration activities in Thrust Belt Systems.
The Niobrara Petroleum System of the U.S. Rocky Mountain Region is a major tight petroleum resource play.
El geocientífico visitante Juan Pablo Lovecchio revisa aspectos generales de la ruptura, grietas y formación pasiva de márgenes y evolución a través del tiempo, así como elementos del desarrollo del sistema petrolero.

Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.
Visiting Geoscientist Juan Pablo Lovecchio reviews general aspects of rifting, rifts and passive margin formation and evolution through time, as well as elements of petroleum system development.
There are approximately 1,000 oil and gas fields in the world that have been classified as 'giant,' containing more than 500 million barrels of recoverable oil and /or 3 trillion cubic feet of gas.
Upon successful completion of this course, you will be able to describe faults and fractures in carbonates, black shales, and coarser clastics as they occur in the northern Appalachian Basin.
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.
