Total U.S. dry gas production is — bcf/d, almost entirely from
horizontal-drilled shale plays. The Marcellus / Utica formation in Pennsylvania,
West Virginia, and Ohio is the largest single source — roughly a third of national
output. The Permian story isn't about gas wells; it's associated gas coming
up alongside crude oil, growing as oil drilling grows. Haynesville in
Louisiana–Texas is the swing producer that responds fastest to price.

SOURCE · U.S. Energy Information Administration, Drilling Productivity Report (DPR,
monthly) for per-basin output, cross-checked against the Natural Gas Monthly's national
total. The DPR's five regions don't cover 100% of U.S. production — Gulf of Mexico,
Bakken, conventional onshore Rockies, and the rest sit outside these basins and make up
the remainder. Per-basin numbers are seeded allocations of the live national production
until the DPR series IDs are wired into update_data.py.
