The Permian region’s marketed natural gas production (green line in chart below) grew from 17.2 Bcf/d in 2021 to 27.6 Bcf/d in 2025, a 60% increase, the Energy Information Administration said in a June 18 report, citing its latest Short Term Energy Outlook (STEO). Over the same period, crude oil production (blue line) grew by 39%, going from 4.7 MMb/d to 6.6 MMb/d.
The gas-to-oil ratio (GOR) in the Permian region has steadily increased over the past five years. In 2025, the GOR averaged nearly 4.2 Mcf of natural gas per barrel of oil (mcf/bbl), a 16% increase from 2021. As the region matures, GOR levels are expected to continue to increase.
In 2021, the Permian produced 17.3 Bcf/d of natural gas and 4.7 MMb/d of crude oil, and the GOR averaged 3.6 Mcf/bbl. If the GOR had remained the same as in 2021, the Permian region would have produced only 23.8 Bcf/d of natural gas in 2025, 14% less than actual production that year.
