Press Play to watch oil and gas leasing spread across Mahoning County, Ohio, parcel by parcel, as acreage and lease counts build over time. Leases are placed on the date they were signed, but they are often recorded with the county weeks or months later, so the most recent months are incomplete and will keep growing.
The last few months are incomplete. Leases are recorded after they are signed, and the delay varies. Of leased parcels, 37% were recorded 2+ months after signing, 24% 3+ months, 11% 4+ months, 3% 5+ and 2% 6+ months (average 57 days, median 37; each of 1,730 parcels counted once, by its first lease). The shaded months are incomplete as of the latest recording (Nov 2, 2026), and incompleteness increases from left to right.
