Mount Vernon, New Harmony, Poseyville: we buy minerals and royalties throughout Posey County, the Griffin Consolidated field and the busiest oil county in Indiana.
Posey County is where Indiana oil actually happens. The Griffin field along the Wabash has paid royalties since before the war, Welborn and West Hovey fill in the middle of the county, the Mount Vernon waterfloods cover the south, and the few new wells Indiana drills each year land here more often than anywhere else. If your family has a Posey County check, it is probably small, probably old, and probably more durable than you think.
What produces here. Oil from Griffin Consolidated, Welborn Consolidated, Welborn North, West Hovey, Mt. Vernon Consolidated, Lamott Consolidated, Springfield Consolidated, and Blairsville East, in Pennsylvanian sands and the Mississippian Degonia, Clore, Palestine, Waltersburg, Tar Springs, Hardinsburg, Cypress, Aux Vases, Ste. Genevieve, Salem, and Warsaw, with the newer wells going to the Fort Payne at 3,800 to 4,300 feet. Indiana publishes production only statewide, not by county: the Division of Oil and Gas reported 115,486 barrels and 239,449 Mcf for July 2026 and 1,315,471 barrels and 2,887,306 Mcf for all of 2025, and Posey carries a large share of it. The operators you will see on checks and in the county records include Citation Oil and Gas, which deepened six New Harmony Realty Corporation wells to the Warsaw in Griffin Consolidated in 2025 and completed two more in June and July 2026; Campbell Energy, with its Fort Payne program in Griffin, the Brooks wells near 4,000 feet, Ribeyre injection conversions in September 2025, and the Terry 1 and 2 permits of October 2025; CDG Operations, converting East Mt. Vernon Unit and Hoehn wells to injection in Lamott Consolidated in early 2026; Moore Engineering, which completed Graulich Farm in April 2025 and Camelot Farms in September 2025 near 3,900 feet; MAP Oil, drilling the Springfield Unit wells and permitting Elbert and Williams in June 2026; Maha Energy, Wade Oil, Howard Energy, Parker Exploration, Winn Oil, Countrymark, and Revitalize Resources. June 2026 alone brought four Posey permits, and the state's active operator list of August 2026 shows Citation with 176 Indiana wells, Campbell with 189, and CDG with 246.
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 Indiana.
