US natural gas prices were modestly higher for the week, amid a bullish storage build and lingering heat across much of the country.
In the futures market, the Nymex front-month contract ended the week at $2.899 per million British thermal units on Friday, up from $2.820/MMBtu on Sept. 11.
Natural gas spot prices rose to $3.01/MMBtu on Wednesday, up $0.20/MMBtu, according to the US Energy Information Administration's Weekly Gas Storage Supplement, released on Thursday.
This was primarily attributed to above-average temperatures across most of the South and Southwest, even as the heat retreated across the North and Northwest.
Above-normal temperatures, however, are expected to blanket almost the whole of the country from Sept. through Oct. 1, keeping cooling gas demand elevated, according to the National Weather Service.
Total US gas consumption dipped by 1%, or 0.8 billion cubic feet per day, largely due to a 1.2 Bcf/d, or 3% decline in power sector consumption, according to data from S&P Global.
Meanwhile, LNG export feedgas flows edged lower during the week, at 18.6 Bcf/d, below the 30-day moving average of 18.78 Bcf/d, according to the Bloomberg LNG Feedgas Model.
The net injection of working gas into storage, for the week ended Sept. 11, was 44 Bcf, up from last week's 40 Bcf, bringing total gas inventories to 3,298 Bcf, according to the EIA's weekly inventory data.
However, the inventory gains were below the forecast net build of 49 Bcf, the prior year's build of 75 Bcf, and the five-year average of 74 Bcf for this period, according to data compiled by Investing.com, making it a fairly bullish report.
At 3,298 Bcf, inventories were 118 Bcf, or 4% above the five-year average for this period, but 122 Bcf, or 4% below the same period last year.
Most regions reported a net injection into storage during the week, with the Midwest showcasing the highest, at 26 Bcf, bringing its total inventories to 934 Bcf. The South Central and Pacific regions, however, reported net withdrawals of 5 Bcf and 1 Bcf, respectively.
Pinebrook Energy Advisors noted that as the storage cushion continued to narrow, the market could see additional support, "even as generation demand begins to ease."
A total of 36 LNG carriers departed US ports during the week, the same as last week, with a total combined capacity of 138 Bcf, up 1 Bcf from last week.
Meanwhile, the US gas rig count increased by two from 132 the previous week to 134 in the week ending Sept. 18, according to data from Baker Hughes (BKR) released Friday. A year earlier, the US had 118 gas rigs in operation.
The consolidated North American oil and gas rig count, a key early indicator of future production levels, decreased by six to 792 from 798 the previous week.
In international markets, European TTF gas prices averaged $27.26/MMBtu for the week ended Sept. 16, $1.79/MMBtu above the prior week. Meanwhile, the Japan-Korea Marker averaged $25.44/MMBtu, about $1.14/MMBtu above the prior week.
