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.
