EQT Corporation(EQT)
EQT Corporation (Pittsburgh, PA; NYSE: EQT) is the largest US natural gas producer by volume and operates significant underground gas storage assets in West Virginia and Pennsylvania. EQT's storage is integrated with its Appalachian Basin production — depleted reservoir fields that serve as both production infrastructure and seasonal storage. EQT's storage fields in West Virginia (including storage along the Equitrans Midstream system, now an EQT subsidiary after the 2024 Equitrans acquisition for ~$5.5 billion) give EQT direct control over Appalachian gathering, compression, and storage. Equitrans Midstream operated the Mountain Valley Pipeline (MVP, ~303 miles from West Virginia to Virginia, completed June 2024) and associated gathering systems that include storage infrastructure. EQT's storage capacity is approximately 45 Bcf of working gas across its storage fields.
