US natural gas prices fell to around $2.74 per million British thermal units on Tuesday after a two-day advance, pressured by record production, ample inventories and weaker demand from LNG export facilities. Lower 48 output averaged 111.5 billion cubic feet per day in August so far, up from July's record 110.7 bcfd, while inventories stood 6.7% above the five-year seasonal average. Gas flows to the nine major US LNG export facilities eased to 17.1 bcfd so far this month from 17.2 bcfd in July, with lower intake at Cheniere Energy's Corpus Christi LNG plant indicating that maintenance is continuing. Weather forecasts turned slightly cooler than previously expected, but above-average temperatures across Texas and the Southwest through Sept. 7 are expected to keep air-conditioning demand elevated.
