What HG Energy does

HG Energy, LLC was a privately held independent upstream and midstream energy company headquartered in Parkersburg, West Virginia, that produced natural gas and oil from assets concentrated in the Appalachian Basin. The company's upstream portfolio included Marcellus Shale natural gas production and conventional oil production supported by two full-scale secondary-recovery waterfloods, with HG Energy identified as the only operator in West Virginia actively developing additional waterflood acreage at the time of its acquisition. Its assets traced their provenance to South Penn Oil/Pennzoil Company holdings previously controlled by East Resources, Inc., from whom HG Energy purchased the original properties at its January 2011 founding.

The company's midstream infrastructure comprised approximately 200 miles of owned gas gathering pipeline (steel and plastic, up to 24 inches in diameter, operating at varying pressures) connecting its producing areas in West Virginia to several major interstate and intrastate pipeline systems for delivery to downstream markets. HG Energy monetized production through commodity sales of natural gas and oil at prevailing market prices indexed to benchmarks such as Henry Hub, with midstream activities generating gathering and throughput economics on its owned systems. Customer segments were wholesale commodity markets accessed via pipeline capacity rather than named downstream counterparties.

In December 2025, Antero Resources Corporation announced definitive agreements to acquire HG Energy's upstream assets for $2.8 billion and Antero Midstream to acquire the midstream assets for $1.1 billion, totaling approximately $3.9 billion. The transactions, which added 385,000 net acres, over 400 drilling locations, and 850 MMcfe/d of Marcellus production to Antero, closed in early February 2026, ending HG Energy's status as an independent operating company. Prior to the acquisition, the company had been backed by Quantum as sponsor and operated with a workforce of 51-100 employees under CEO Jared Hall and COO Eric Grayson.
