Historic Oil Field
New Harmony Consolidated was discovered in 1939 along the Wabash River, spreading across White County and neighboring Illinois counties with productive extension into Indiana on the far bank. It produces from Mississippian Cypress and Waltersburg sandstones and McClosky oolitic limestone, and it anchors what remains the most productive oil county in Illinois: White County produced more than 2.2 million barrels in 2024, over thirty percent of the state total. For mineral and royalty owners, that means an active operating environment — but at stripper rates, sustained by waterflood rather than by new field development.
New Harmony came in during 1939, at the tail of the 1937 to 1940 discovery wave that revived Illinois oil. The field was consolidated across White, Wabash and Edwards county acreage, and it takes its name from the historic town of New Harmony on the Indiana side of the Wabash. Development moved quickly across river-bottom and upland farm ground alike, and the leasing of that era created the dense pattern of small tracts and mineral reservations that still defines White County royalty ownership.
Because the field straddles the state line region, its development history involves both Illinois and Indiana operators and regulators, and gas injection into the McClosky limestone was tested in the adjoining New Harmony and Griffin fields as an early enhanced-recovery experiment. Through the postwar decades the field settled into waterflood operation, with injection maintaining pressure in the Cypress and Waltersburg sandstones. Operatorship consolidated among Illinois Basin independents who specialize in low-cost operation of mature sandstone reservoirs.
White County’s modern standing tells the story of the field’s durability. In 2024 the county produced more than 2.2 million barrels — more than the next four Illinois counties combined and over thirty percent of statewide output, its best year since 2020. That leadership rests on maintaining and reworking a very large inventory of existing wells rather than on new discoveries. The royalty base underneath it has been divided by inheritance for more than eighty years into small undivided fractions.
New Harmony produces from the Chesterian sandstone-and-limestone sequence that defines Illinois Basin production. The Cypress Sandstone is the primary reservoir, a channel and bar sandstone with good porosity where well developed; the Waltersburg sandstone adds shallower pay; and the McClosky oolitic limestone provides carbonate porosity in oolite shoals. Traps combine gentle structure with stratigraphic pinch-outs along the Wabash River trend. Sand continuity varies, so individual leases perform quite differently, and stacked pay means a single tract may be charged with production from more than one horizon.
Waterflood is the operating reality across New Harmony, with injected water sweeping the Cypress and Waltersburg sandstones toward producing wells. Gas injection into the McClosky limestone was tested historically in this area as an alternative recovery method, part of the long record of experimentation in the Wabash River fields. Today the field behaves like the rest of the mature basin: high water cuts, low oil rates per well, and economics governed largely by the cost of lifting and disposing of produced water. Sustained injection, not new drilling, keeps royalty payments flowing.
White County royalty interests benefit from something many mature provinces lack: a deep bench of operators who actually want to run these wells, which shows up in continued high county-level production. Even so, individual interests are small and their value depends on the lease, the producing horizon and flood support — not on the county’s headline numbers. We underwrite the specific tract and are candid about stripper economics. Pointer Minerals buys direct: we buy minerals and royalties in White County and provide free written offers.
County-level well data, production charts, and selling guides for the counties this field spans:
It helps at the margin, because an active operating base means wells are more likely to be maintained, reworked and kept online rather than plugged. But county-level totals do not determine the value of your specific decimal. What matters is the lease under your tract, which zone it produces from, and whether it has injection support. We look at those directly.
Only if your minerals actually cross the state line, in which case Indiana tracts are conveyed and recorded under Indiana law separately from the Illinois tracts. Within White County it is a normal Illinois conveyance. We confirm the legal descriptions and the governing state for each parcel before drafting anything.
Compare it to what the interest would realistically pay you over time, net of the risk that wells are shut in or plugged, rather than to a headline per-acre figure from a different basin. Ask what production and flood assumptions the buyer used. We put our offers in writing with the reasoning available, so you can weigh them against simply keeping the interest.
