New on Enercast: daily U.S. gas supply by basin

Enercast’s Supply / Production page now shows where the gas is coming from. A new By Basin table breaks the national supply figure into Appalachia, the Haynesville, the Permian and eight more basins, updated every day from actual pipeline nomination data.

What you get

• Each basin’s receipts for the last six gas days, with the day-on-day change against the same nomination cycle and the change in the 7-day average.
• Trend lines for each of the major basins.
• Rows that add up exactly to the national total, so a move in the headline number can be traced to the basin behind it.

The basins: Appalachia (with its New York, Virginia and Kentucky fringe), Haynesville / East Texas, Permian (with the long-haul pipelines that carry Permian gas to the Gulf Coast), Eagle Ford / Gulf Coast, Gulf of Mexico offshore, Midcontinent, North Texas, Fayetteville, Rockies, San Juan and Bakken.

Why it matters

A national number tells you supply moved. The basin table tells you where. On November 1, U.S. receipts fell 3.26 Bcf/d in a day; the basin rows showed almost all of it in two places, Appalachia (−1.71 Bcf/d) and the Haynesville (−0.76), while the Permian was flat. Read that story.

How much of each basin we see

Every row shows its coverage. Enercast tracks gas where it enters interstate pipelines, so basins that ship mostly on interstate systems are well covered — about 85% of Appalachia and 80% of the Haynesville — while the Permian row is interstate receipts only, around 20% of the basin, because most Permian gas moves on intrastate pipelines first. Read the Permian row as a direction, not basin output.

The basin table is free on the website, updated daily by 7:30 AM ET. Pro subscribers get the figures by 2:45 AM ET with intraday change alerts, and basin history in the Excel/CSV downloads.
