Carmi, Grayville, Crossville: we buy minerals and royalties throughout White County, the New Harmony Consolidated field and the top oil county in Illinois.
White County is the Illinois Basin's volume county and the one place in the state where a mineral owner can still expect to see a rig. It produced 2,100,336 barrels in 2025, nearly a third of everything Illinois made, and the ISGS well database carries about 4,900 unplugged oil producer records and 900 active water injection wells here. Most of what we buy in White County is a small decimal in a consolidated waterflood unit leased to someone's grandparents, paid monthly for decades.
What produces here. The Illinois Petroleum Resources Board puts White County at 2,100,336 barrels for calendar 2025, down from 2,201,158 in 2024 but still first in the state by a wide margin over Marion. The oil comes from New Harmony Consolidated, discovered in 1939 and shared with Wabash and Edwards counties, and from Roland, Phillipstown, Herald, Storms, Maunie, Concord, Inman East, Trumbull and Mill Shoals, with pay in the Waltersburg, Tar Springs, Cypress, Aux Vases, Ste. Genevieve and McClosky and, in the newer wells, the Ullin and Fort Payne at 4,100 to 4,500 feet. The operators you will see on checks and in the county records include Citation Oil and Gas, which bought Noble's southeastern Illinois leases in 2010 and reports more than 118 recompletions and deepenings in the New Harmony area into the Salem, St. Louis and Warsaw, Campbell Energy of Carmi, the largest producer in the basin, Keepes Petroleum, Brookston Resources, Herman L. Loeb, Patrick Webb Oil, Shawnee Exploration Partners, Mountain View Oil and CountryMark Energy Resources. Drilling is steady: the IDNR weekly permit logs for 2025 list 64 oil well permits in White County, 20 of them Citation's and 8 Campbell's, and 2026 through late October shows at least 47 more, including Citation's Westfall 29-1 and Keepes Petroleum's Glaze Five 30-1 in October 2026, almost all of them Ullin and Fort Payne tests.
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.
New Harmony Consolidated, discovered in 1939 and shared with Wabash and Edwards counties, plus Roland, Phillipstown, Herald, Storms, Maunie, Concord and Mill Shoals: the fields that make White County nearly a third of the state's oil.
Waltersburg, Tar Springs, Cypress, Aux Vases and the McClosky, the shallow Mississippian pay that most White County royalties have been built on since the 1940s, much of it under waterflood.
The deeper Valmeyeran carbonates at 4,100 to 4,500 feet, the target of most new White County permits in 2025 and 2026 and of Citation's recompletion and deepening program in the New Harmony area.
