Earlier this month, the Potential Gas Committee released the highest assessment it ever has on the amount of producible natural gas in the United States, according to E&E News. The group of industry experts announced the amount of producible natural gas is up roughly 20% since its last assessment two years ago.

The increase of 557 trillion cubic feet (tcf) reported is the highest assessment in the Potential Gas Committee’s 54-year history. The organization puts total recoverable resources at 3,374 tcf — enough to sustain current levels of U.S. natural gas consumption for over a century.

The latest evaluation “confirms that the U.S. has an abundance of natural gas” in onshore and offshore reservoirs, said Alexei Milkov, the group’s executive director, in a press release.
