If you’re referring to the U.S. share of global production, the increase has been remarkable.
Crude oil
- 1999: about 8–9% of global crude oil production.
- Today (2025–26): about 20–22% of global crude oil production.
That means the U.S. share has risen by roughly 12–13 percentage points, or more than doubled (around a 140–160% increase in market share).
Natural gas
- 1999: about 18–19% of global natural gas production.
- Today (2025–26): about 25–26% of global natural gas production.
That’s an increase of roughly 7 percentage points, or around a 35–40% increase in global market share.
The change has been driven overwhelmingly by the shale revolution, beginning in the mid-2000s with hydraulic fracturing and horizontal drilling. The U.S. went from being expected to become a major importer of both oil and gas to becoming:
- the world’s largest crude oil producer (since 2018), and
- the world’s largest natural gas producer (since about 2009).
In absolute terms, U.S. crude oil production has risen from roughly 5.9 million barrels per day in 1999 to around 13.5–14 million barrels per day today, while natural gas production has approximately doubled over the same period.
