Financial firm LSEG said average gas output in the U.S. Lower 48 states was up to 111.6 billion cubic feet per day so far in August, up from a monthly record high of 110.7 bcfd in July.
Record output and mild spring weather this year have allowed energy firms to keep the amount of gas in inventory higher than the five-year (2021 to 2025) average since March.
Gas inventories have remained in surplus despite weeks of above-normal temperatures this summer.
"With the short-term temperature views now favoring some comparatively cool patterns across most of the heavily populated northeast quadrant of the U.S., the process of reducing significant (supply) surplus will be further challenged going forward ahead of the low demand shoulder period when it becomes increasingly difficult to shift a supply surplus significantly in either direction," consultancy Ritterbusch & Associates said in a note.
Meteorologists forecast milder weather than previously expected nationwide in the coming weeks, as Cooling Degree Days fell to 212 on Tuesday from 216 on Monday. CDDs measure energy demand to cool buildings.
LSEG projected average gas demand in the Lower 48 states, including exports, would slip from 114.4 bcfd this week to 112.7 bcfd next week. The forecast for next week was lower than LSEG's outlook on Monday.
Average gas flows to the nine big U.S. LNG export plants stand at 17.2 bcfd so far in August, unchanged from July and slightly lower than a monthly record high of 17.4 bcfd in June.
