U.S. natural gas production in recent days has plunged more than 3 Bcf/d. While some Gulf of Mexico offshore and Gulf Coast production is still offline from the recent tropical storms, the bulk of these declines are happening in the Northeast, where gas production has dived 2 Bcf/d in the past week or so to about 30.2 Bcf/d, the lowest level since May 2019, pipeline flow data shows. Appalachia’s gas output was already down earlier in the month, as EQT Corp. shut in some volumes starting September 1. But with storage inventories soaring near five-year highs, a combination of maintenance events and demand constraints are forcing further curtailments of Marcellus/Utica volumes near-term. Today, we provide an update of Appalachia gas supply trends using daily gas pipeline flow data.
