Working natural gas inventories totaled 2,930 billion cubic feet (Bcf) in the Lower 48 states as of July 7, according to our Weekly Natural Gas Storage Report. U.S. natural gas production has outpaced demand, resulting in more natural gas injected into storage midway through the 2023 refill season (April 1–October 31). Since April 1, net injections into natural gas storage have exceeded the five-year (2018–22) average by 6% (66 Bcf), and working natural gas inventories have reached 69% of working gas capacity so far this refill season.

The increased surplus of working natural gas inventory has reduced natural gas prices during the first half of this year. Last summer, large deficits to the five-year average contributed to high natural gas prices, and the daily near-month futures price rose above $9.00 per million British thermal units (MMBtu) on several occasions. When the deficit to the five-year average eased late last summer, prices began to fall. Working natural gas stocks have been at a surplus to the five-year average since January 2023. This surplus reached a high in March and has remained above average since the start of refill season in April. Prices began to decline in January from an average of $5.53/MMBtu in December 2022 and have averaged below $2.50/MMBtu since February.
