Exploration Adventures in France’s Aquitaine Basin

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

Seeking Informed Dissonance

Listening to “Marcia Funebre” from Beethoven’s Symphony No. 3 as I write prompted me to think about what I have been hearing. Certainly, a wide range of emotions, from triumph and happiness to the misery of loss, along with beautiful dissonance. That’s why people listen to Beethoven again and again. Leaders are reminded repeatedly to publicly support decisions made by boards, even when they disagree. However, when decisions are made in an environment of misinformation, that best practice of publicly supporting decisions becomes insupportable.

Foundation Supports ‘The Ocean on Top of Our Mountain’ Animated Series

An innovative animated series aimed at young children that tells the story of the Indian subcontinent’s epic tectonic history in creative and even entertaining ways is now closer to reality, thanks to the AAPG Foundation. Trustees have approved initial support for “The Ocean on the Top of Our Mountain,” which graphically tells the story of the region’s 5,000-mile migration northward from Gondwana to its collision with Asia.

Frontier Exploration in the Rocky Mountain West

There are times when national and local forces combine in such a way that the entire hydrocarbon value chain is realized in a frontier area over the course of only a few years. Such was the case for the natural gas fields in southwestern Wyoming over the decades of the 1920s to the ‘40s.

A Bond Forged in Road Trips and Geoscience

Here’s one sign of change in university- level geoscience education: This year, for the first time, both recipients of AAPG’s Grover E. Murray Memorial Distinguished Educator Award are female geology professors. Their careers have followed different paths and include contrasting professional interests, but the stories of their respective educational histories share several common links. That story starts with James Taylor. And chocolate chip cookies.

Taking an Introspective Turn

Listening to “Simple Song” as I write prompted me to think about choosing to go it alone. As we know, geologists do not go it alone – we engage in a vibrant and diverse community and across disciplines to solve many of the world’s biggest problems, starting with water and energy and extending into topics like mineral resources and natural hazards. AAPG is a pillar of the geoscience community and its members engage with geoscientists, engineers and other energy professional internationally. AAPG members are rightfully proud of the vital work we do.

Developing Tight Oil Resources in the Middle East

When the International Petroleum Technology Conference comes to Saudi Arabia in February, the technical program will include a significant look at both unconventional oil and gas and conventional tight oil in the Middle East. Those are two different concepts in the region and the distinctions are important. The Middle East holds a large conventional tight oil resource, now emerging as a serious focus for development. With so much recent attention devoted to unconventional resources, conventional tight oil could be considered an overlooked sibling.

How to Grow Big Fields into Giants

Thanks to continuing advances in reservoir characterization, technology and innovative thinking, many oil fields around the globe have “grown larger” in recent decades. John Sneider, president of Sneider Exploration Inc., documented examples of mature field growth 20 years ago and recently revisited the topic to focus on mature giant fields. This updated analysis is detailed in chapter 4 of the new AAPG Memoir 125: “Giant Fields of the Decade: 2010 – 2020.”

Unsupervised Machine Learning for Characterizing a Geothermal Sandstone Reservoir

The estimated hydrocarbon reserves around the world, when produced, can keep us going for the next several decades. But scientific records and our own experiences are enough evidence that climate change is indeed happening. Addressing it requires energy extraction from non-fossil fuels. One such resource is the natural heat of the Earth, or geothermal energy.

Making It All Work

Before unconventional resources became prevalent in the global petroleum supply, deepwater exploration and development was a significant focus for many larger companies. For deepwater activities to succeed, the petroleum industry was forced to merge its above-ground concerns with the below-ground geoscience and engineering disciplines.

Introducing the New EXPLORER, New Digital Newsletters

Perhaps you did a double take pulling the April issue of EXPLORER from the mailbox. What is this? If you joined AAPG in the last 40 years, you’ve only known EXPLORER in its long-standing tabloid format. It worked well for many years as our advertisers – particularly seismic companies – loved the large format and the ability to display their data on a sweeping canvas. For readers, it was a little more awkward.
