This Month's Explorer Articles

Do super basins have a role in sustainable development? The short answer is, Yes. Super basins can be part of a sustainable energy and environmental future for the planet. A more complex answer is: It depends on how you define “sustainable.” In the view of the oil and gas industry, sustainability has an economic component and an environmental component. Hydrocarbon-based energy is essential for a sustainable world economy in that view, and it will be for a long time to come.

In the business of oil and gas exploration, it’s all about managing risk. Companies are more likely to drill where there are strong indications of hydrocarbons from field and seismic data, nearby wells and discoveries – and preferably, all of the above. So, when the federal government officially opens the doors in the near future to the Coastal Plain of the Arctic National Wildlife Refuge for commercial drilling, it could be like watching a game of poker.

The Mars 2020 Perseverance Rover launched on July 30, 2020, toward Mars. The Perseverance landing is planned for Feb. 18, 2021 at Jezero Crater in the Nili Fossae region of Mars. According to rover science team members Sanjeev Gupta and Briony Horgan, the mission science goal will be “to explore the history of water and chemistry in an ancient crater lake basin and associated river-delta environments to probe early Martian climates and search for life.” The Mars 2020 spacecraft is currently halfway to Mars, traveling at about 100,000 kilometers per hour, relative to the Sun. It will take about six months (203 days) to traverse the 480 million kilometers from Earth to Mars on a sweeping Hohmann Transfer Orbit.

“Machine learning” has become a common phrase in geophysics. These methods, based on complex algorithms and statistics, allow geoscientists to speed up and improve their interpretations. However, as interpreters, we can feel intimidated and concerned about how much of our expertise can be replaced by machine learning algorithms. To better understand the limitations, we assess the importance of human validation and participation in one machine learning process, highlighting the upsides and downsides of a machine-derived process versus a geoscientist-guided selection of attributes. As Earth scientists, we explored a suite of seismic attributes and selected those that were meaningful for interpreting a deepwater channel system and compared our results with the attributes derived from principal component analysis.

Associations exist to serve their members, and AAPG is no exception. Those of us who have the privilege of holding leadership positions in our Association have the responsibility to listen and respond to members’ comments and concerns. I am writing address questions that our leadership team has received about why we ask presenters and committee members to pay a registration fee to participate in virtual events that they support with their time and expertise.

The month of July 2020 was indeed an eventful one on AAPG’s calendar, as various divisions and regions of our great Association underwent changes in leadership. The young professionals arm of AAPG Africa Region was not left behind, as the baton of leadership was passed to Philip Ajaebili, ably supported by AAPG Africa Region Program Manager Delia Kuye, AAPG Middle East and Africa Region Director Abeer Zubaidi and a team of dedicated YP representatives in several African countries to build on the great efforts of past leaders and YP representatives in the region.

Emma Giddens was a California girl who fell in love with carbonate rocks, excelled in nearly everything she tried, led her IBA team to a Selley Cup victory and even as a graduate student was known internationally for her “pioneering” research. In fact, professors at three schools marveled at her passion for geology, her intelligence, her kindness and mentorship of fellow students. Tragically, Giddens died shortly after receiving word that her research was being honored with an AAPG Foundation Grant-in-Aid.

By the time you are reading this I hope you have attended your first virtual AAPG Annual Convention and Exhibition – ever! What a success it was, with up to 10 concurrent sessions including talks and posters. Our own Claudia Hackbarth and Mike Bingle-Davis chaired a session on the future of oil and gas and Bill Ambrose chaired one on expanding energy frontiers to Earth, the moon and Mars. A new format was offered with live presentations and interactive panels that were moderated and conducted by experts in their fields.
