Fairmont, Mannington, Fairview: dry to lean Marcellus over one of West Virginia's oldest gas fields, with longwall coal shaping where anything can be drilled.
Marion County is dry to lean Marcellus in northern West Virginia, with moderate active development on top of a very old shallow gas base. The Mannington field is one of the oldest gas fields in the state, and roughly 678 wells produce today out of about 2,400 on file.
The defining feature is coal. Pittsburgh seam longwall mining, now operated by Core Natural Resources following the Consol and Arch merger in January 2025, runs under most of the county, and coal is severed under most of it as well. Longwall mine planning materially constrains where pads and laterals can go, which means development timing on a Marion County tract is a real variable rather than an assumption. Any valuation that ignores it is incomplete.
Marion's mining history also produced unusually deep and tangled severance chains, and Fairmont field era flat rate leases are common. Under W. Va. Code section 22-6-8 those flat rate instruments convert to a minimum one eighth royalty that may not be diluted by post production costs.
On deductions generally, West Virginia is the most owner favorable state in the country: Wellman and Tawney require a deduction clause to expressly provide for the cost, identify the deductions with particularity, and state the calculation method, and Romeo v. Antero extended the point of sale rule in June 2025.
