US natural gas futures were essentially flat in after-hours trading on Friday, as strong production and healthy inventories limited gains despite late-summer heat supporting demand.
The front-month Henry Hub contract and the continuous contract both edged down by a modest 0.07% to $2.899 per million British thermal units.
Fundamentals remained broadly balanced as late-summer heat across much of the US supported demand, while cooling needs were expected to fade ahead of autumn.
"Pervasive warmer-than-normal weather has kept generation load elevated, but record production and generally healthy storage inventories continue to keep a lid on pricing," Pinebrook Energy Advisors said.
Celsius Energy said power burn for the week ended Sept. 17 was 42.7 billion cubic feet per day, up 2.3 Bcf/d from the same week a year earlier, underscoring the impact of above-average temperatures across much of the country in mid-September.
Looking ahead, the Commodity Weather Group said Friday that forecasts had shifted cooler, with above-average temperatures now expected to cover a smaller portion of the South and Southeast from Sept. 23 to Oct. 2. The shift reduced estimates for early autumn air-conditioning demand.
LNG exports continued to support demand. Estimated net gas flows to US LNG export terminals remained strong at 19.2 Bcf/d on Friday, up 0.7% from a week earlier.
The US Energy Information Administration said LNG-carrying capacity on the 36 vessels that departed US ports during the week ended Sept. 16 was 138 Bcf, up 1 Bcf from the previous week. The number of tankers was unchanged.
Total Lower 48 state gas demand was 75.7 Bcf/d on Friday, down 0.6% from a year earlier, Barchart said, citing BNEF data.
On the supply side, US Lower 48 dry gas production was 113.8 Bcf/d on Friday, up 4.9% from a year earlier.
The EIA's weekly report on Thursday was supportive of natural gas prices, showing a 44 Bcf increase in US natural gas inventories for the week ended Sept. 11. The build was below expectations for around a 48 Bcf increase and the five-year weekly average of 74 Bcf.
Natural gas inventories were down 3.9% from a year earlier but remained 3.7% above the five-year seasonal average, indicating adequate supplies.
