Louisville, Flora, Clay City: we buy minerals and royalties throughout Clay County, the namesake end of the Clay City Consolidated field.
Clay County gave its name to one of the six fields that make up half the Illinois Basin, and then watched most of the drilling move next door. Clay City Consolidated has been producing since 1937, the ISGS database carries about 2,200 unplugged oil producer records here against 2,900 plugged, and what we buy in the county is almost always a legacy royalty: small, steady, and inherited.
What produces here. The Illinois Petroleum Resources Board puts Clay County at 244,337 barrels for calendar 2025, seventh in the state, down from 270,307 in 2024. The oil comes from Clay City Consolidated, shared with Wayne and Richland counties, and from Sailor Springs Consolidated, Iola Consolidated, Ingraham Consolidated, Kenner, Louisville, Xenia East and Hord, with pay in the Salem, Ste. Genevieve, Cypress, McClosky and Aux Vases. The Pure Oil and Union Oil of California names are still on the historical records; the operators you will see on checks and in the county records today include Elysium Energy, Gator Oil, Citation Oil and Gas, Deep Rock Energy, Kuebler Ultra Oil and Dee Drilling. Drilling is close to nil: the IDNR weekly permit logs show one injection permit in 2025, Kuebler Ultra Oil's Hartley 12 in the Benoist, and two oil well permits in 2026, Deep Rock Energy's DRE Brooks 1 on May 18 and DRE-Lewis 1 on July 14, both to the Fort Payne at 3,800 feet in Township 5 North, Range 7 East northeast of Louisville.
Whatever you own here, producing royalties, non-producing acreage, or an inherited fraction split among family, we will identify it from whatever paperwork you have, value it off the actual wells and activity, and show you the reasoning with the offer. Free, no obligation, and no pressure: if keeping it is the right answer, we will say so. Inherited it? Start with inherited mineral rights in Illinois.
