Gastar Exploration Inc. functioned as an autonomous energy enterprise within the United States. Its operations centered on the discovery, cultivation, and extraction of diverse hydrocarbons, encompassing crude oil, condensate, natural gas, and natural gas liquids (NGLs). The company's core business model involved locating, securing, and subsequently developing oil and natural gas assets, with a pronounced focus on non-traditional reserves, notably shale plays. Gastar commanded a significant land footprint strategically situated in the central region of Oklahoma's STACK Play. This area is distinguished by its abundant, multi-zone hydrocarbon-bearing geological formations, including the Meramec and Osage formations (part of the broader Mississippi Lime), the Oswego limestone, the Woodford shale, and the Hunton limestone formations.
