McLeansboro, Dahlgren, Broughton: we buy minerals and royalties throughout Hamilton County, Dale Consolidated and the Aux Vases, with Bi-Petro drilling Ullin wells south of town.
Hamilton County is Dale country, the middle of the three-county Dale Consolidated field that came in in 1940, and it is one of the few places in Illinois outside White County where a landowner can still watch a rig move in. Bi-Petro has been permitting Ullin wells south of McLeansboro at a steady clip for three years. Most of what we buy here, though, is older: an Aux Vases royalty under a lease signed before the war.
What produces here. The Illinois Petroleum Resources Board puts Hamilton County at 222,005 barrels for calendar 2025, tenth in the state, down from 264,414 in 2024. The oil comes from Dale Consolidated, shared with Franklin and Saline counties, and from Roland Consolidated, Mill Shoals, Bungay Consolidated, Aden Consolidated, Walpole, Enfield, Thackeray, Dahlgren and Long Branch, with pay in the Aux Vases above all, then the Ste. Genevieve, McClosky, Ullin and Warsaw; the ISGS database carries about 1,480 unplugged oil producer records here. Shell and the Texas Company are still on the historical records; the operators you will see on checks and in the county records today include Bi-Petro of Springfield, Patrick Webb Oil, Brehm Oil, Herman L. Loeb and Moore Engineering and Production. The IDNR weekly permit logs show 10 oil well permits in 2025, six of them Bi-Petro's, and at least seven in 2026 through late October, again six Bi-Petro, and every one of the 2026 wells is an Ullin test at 4,225 to 4,400 feet: Bi-Petro's Anselment 3-B and Miller 1-7 in June, Patrick Webb Oil's Webb-Johnson 6 in July, and Bi-Petro's Stratton 1-3 on September 30, 2026, all in Townships 6 South, Ranges 5 and 6 East south of McLeansboro.
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.
Dale Consolidated, discovered in 1940 and shared with Franklin and Saline counties, plus Roland Consolidated, Mill Shoals, Bungay, Aden, Walpole, Enfield, Thackeray, Dahlgren and Long Branch.
More Hamilton County oil wells bottomed in the Aux Vases sand than in any other formation, with the Ste. Genevieve, McClosky and Warsaw alongside; it is the classic Dale pay.
The deeper Valmeyeran carbonate at 4,200 to 4,400 feet, the target of nearly every Hamilton County permit in 2025 and 2026, most of them Bi-Petro's in Township 6 South.
