Working natural gas in storage in the Lower 48 states ended the natural gas refill season (April 1–October 31) with more than 3,900 billion cubic feet (Bcf), according to estimates based on data from our Weekly Natural Gas Storage Report released on November 6. U.S. inventories are starting winter 2025–26 at about the same level as last year, the most since 2016. As of October 31, inventories are 4% above the five-year (2020–24) average after above-average injections into storage throughout much of the injection season.

Natural gas inventories in the Lower 48 states were relatively depleted at the end of March 2025 (the end of withdrawal season), totaling 1,811 Bcf, 21% less than at the same time in 2024 and 2% less than the five-year average for March. Operators injected more natural

Scientists have decoded the atomic-level secrets behind catalysts that turn propane into propylene. Their algorithms reveal unexpected oxide behavior that stabilizes the catalytic reaction by clustering around defective metal sites. The findings could help streamline industrial chemistry and inspire better catalysts for major processes like methanol synthesis.
