Expand Energy 

Expand Energy Corporation functions as an independent entity primarily focused on the discovery and extraction of energy resources throughout the United States. Its core operations involve the acquisition, exploration, and subsequent development of properties to produce crude oil, natural gas, and associated liquid hydrocarbons from subterranean geological formations. The company maintains significant interests in key natural gas production areas, specifically within Pennsylvania's northern Appalachian Basin (Marcellus Shale) and northwestern Louisiana (Haynesville/Bossier Shales). As of December 31, 2023, its asset base featured a diverse collection of onshore U.S. unconventional natural gas properties, including ownership stakes in approximately 5,000 natural gas wells. Established in 1989 and based in Oklahoma City, Oklahoma, the corporation was formerly known as Chesapeake Energy Corporation before officially adopting the Expand Energy Corporation name in October 2024.
