An interactive map of the Illinois Basin across southeastern Illinois, and the core counties where Buckhead Energy buys mineral rights and royalties.
Approximate basin extent and selected counties shown for orientation — not a survey or title map. Click a county to open its mineral-rights page.
The Illinois Basin is one of America's oldest oil regions, centered on the southeastern Illinois counties of Wayne, Wabash, White, Hamilton, Lawrence, and Richland. Most production is conventional and long-lived, so wells decline slowly and many leases have paid royalties for decades.
Because the basin is mature, value usually tracks current check volumes, operator stability, and any waterflood or enhanced-recovery activity rather than new horizontal drilling.
