In-brief analysis

October 31, 2024

Data source: U.S. Energy Information Administration, Short-Term Energy Outlook, October 2024 (Table 10b), and Enverus DrillingInfo
Note: 2024 represents year-to-date data through September. To calculate the barrel of oil equivalent, we use a conversion factor of 6,000 cubic feet of gross natural gas production per 1 barrel of oil.

Natural gas produced from the three largest tight oil-producing plays in the United States has increased in the last decade. Natural gas comprised 40% of total production from the Bakken, the Eagle Ford, and the Permian compared with 29% in 2014.

Combined crude oil and natural gas production from these plays more than doubled over this period as hydraulic fracturing—also known as fracking—and horizontal drilling have allowed producers to access and extract more crude oil and natural gas from tight formations. However,

A remarkable fossil assemblage gets a new interpretation

A team of paleontologists recently discovered that an ancient seascape known for its diverse assemblage of exceptionally preserved fossils represents an unexpected oceanic setting, placing the fossils in an environmental context that is dramatically different from other fossil assemblages of the Cambrian age. The team published their findings in the journal, ScienceAdvances.

The giant trilobite Redlichida rex in outcrop of the Emu Bay Shale.

The team explored the Emu Bay Shale, exposed across a sea cliff in South Australia, and found its strata — the layers of material settled over time — were deposited in an energetic fan river delta at the edge of a tectonically active rift basin, which forms as two continents move apart from each other. These unique features mean gravel and cobbles were catastrophically deposited into the ocean by debris flows that originated on land.

“It’s not where you would expect to see delicate, soft-bodied creatures preserved,” Robert Gaines, a professor at Pomona College, said. “The shale’s unique setting hosted a diverse ecosystem with extraordinary fossil preservation, and now we know that the environmental setting exerted a strong influence on the structure of this early animal community.”

These findings help to explain why the bottom-dwelling fauna was dominated by endemic species, likely inhabiting niche
