Mars Exploration: the Ancient Delta-Lake System in Jezero Crater

NASA’s Perseverance rover successfully landed on Mars on Feb. 18, 2021, which AAPG celebrated with a live watch party. Perseverance has since explored the Séítah region and is currently at the delta front of Jezero Crater on Mars using an enhanced autonomous navigation system and under guidance from NASA/JPL controllers. As of May 13, 2022, Sol 436, Perseverance has traveled 11.4 kilometers and drilled eight core samples. The rover has returned more than 249,000 raw images that are publicly available in the mission multimedia catalog.

The Offshore Technology Conference is Back

In February, TotalEnergies announced a significant light oil discovery in the Orange Basin, offshore Namibia. Reuters reported a source suggesting that the Venus-X1 well may have found more than 1 billion barrels of oil equivalent. This was the second significant discovery announced in the basin that month. The offshore continues to deliver new oil and natural gas discoveries worldwide. And as this issue hits your inbox, the offshore is the primary topic of discussion in Houston as the 2022 Offshore Technology Conference returns to NRG Park from May 2-5.

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.

Is It Time to Resurrect the Lost Art of Conventional Exploration?

These days, more uncertain than the price of gas, especially with the announcement last month from the administration to ban the import of Russian oil and gas, combined with the European Union’s decision to cut imports by 80 percent, is the question of whether the world will get the energy it needs – and who will provide it. To that end, it’s worth considering what conventional oil and gas reservoirs here in America can be drilled and placed online quickly to help fill that need.

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.

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.

Eastern Section Back on Track with Historic Conference

What is “unconventional wisdom?” It’s the wisdom obtained from half a century of important conferences organized by the AAPG Eastern Section, founded in 1971, which recently celebrated at its 50th annual conference in Pittsburgh. The Pittsburgh Geological Society, founded in 1945, co-hosted the conference with the Pittsburgh Association of Petroleum Geologists, created in 1984. “The theme ‘Unconventional Wisdom’ is intended to reflect not only the unconventional resources and reservoirs that have brought life to the Appalachian basin, but also to appreciate the broad heritage of our science and vocation,” said conference General Chair John Corbett.

Big Drilling in Ancient China

It has become something of an old chestnut in the West that China will often claim to have achieved famous scientific advancements and inventions first, often hundreds of years before the West. The investigation of these sorts of disputes – and deciding who gets bragging rights – is probably best left to serious historical researchers, but there is firm evidence of many interesting early technical achievements from the Middle Kingdom. Ancient China’s development of deep drilling techniques predates similar advancements in the West by hundreds of years.

CarbonSAFE Project Uses Core Technology to Identify CO₂ Storage Potential

Increasing global concern about climate change and its impact on the environment and society has led to a variety of strategies to reduce carbon dioxide emissions and to remove CO₂ from the atmosphere and find places to store it. Many companies are hard at work to perfect methods of carbon capture, use, and storage. Franek Hasiuk, associate scientist at Kansas Geological Survey, said CCUS is the best technology available to reduce emissions produced by the global economy. Hasiuk is part of a team of scientists working on the Integrated Midcontinent Stacked Carbon Storage Hub, a project to investigate subsurface geology in southwest Kansas and southwest Nebraska and demonstrate the viability of injecting CO₂ into underground rock layers.

Where Does Unconventional Resource Development Go from Here?

Unconventional resource development has a remarkable history, combining breakthroughs and advances in both technology and geoscience. The pace of progress might have slowed in recent years, but that history is still being written.

Fluid Migration and Accumulation within the Mississippian: Why 2% Oil Cut Here, 15% One Mile Away?

Water cut is a big factor in gauging the success of horizontal drilling in the Mississippi Lime Play (MLP). The contributing factors are related in part to the spectrum of producing lithofacies and reservoir quality encountered that varies laterally and vertically, sometimes dramatically.
