Historic Oil Field
The East Texas Oil Field is the largest conventional oil field ever found in the contiguous United States — a Woodbine sandstone giant some 45 miles long under Gregg, Rusk, Upshur, Smith, and Cherokee counties that has produced billions of barrels since 1930. Today it is a legacy field: production is a small fraction of its historic peak, but tens of thousands of tracts still carry producing royalty interests, and the field’s title history makes East Texas minerals some of the most fragmented — and most frequently inherited — in the state.

Columbus Marion "Dad" Joiner completed the Daisy Bradford No. 3 in Rusk County in October 1930, proving oil in a place the majors had written off. Within months, wells at Kilgore and Longview showed the discoveries were connected — one continuous reservoir of staggering size. The boom that followed reshaped East Texas: Kilgore famously had derricks standing shoulder-to-shoulder downtown, and the flood of unrestrained production crashed oil prices nationally.
The chaos forced historic intervention. In 1931 the governor declared martial law and sent the National Guard to shut the field down; the Texas Railroad Commission’s proration authority was forged in the legal battles that followed, establishing the regulatory model that governed American oil for the next half century. H.L. Hunt’s acquisition of Dad Joiner’s leases became one of the founding fortunes of Texas oil.
The field’s strong natural water drive — the Woodbine aquifer pushing oil updip toward the wells — gave East Texas one of the highest recovery factors of any giant field in the world. From 1942 the East Texas Salt Water Disposal Company began reinjecting produced water on a massive scale to sustain reservoir pressure, an early and enormously successful pressure-maintenance program. Cumulative recovery ultimately exceeded six billion barrels. Today the field produces at stripper-well rates across roughly 180 active leases, but its water-drive mechanism means many wells have produced steadily for generations.
The field produces from the Cretaceous Woodbine sandstone at roughly 3,600 feet, trapped where the sand pinches out updip against the Sabine Uplift. The Woodbine here is clean, porous, and continuous — the reason a single accumulation could stretch across five counties. The aquifer beneath it is the field’s engine: as oil is withdrawn, water advances and maintains pressure, which is why East Texas wells historically declined slowly rather than steeply.
East Texas never needed a CO2 flood — its enhanced recovery story is the water drive itself, actively managed since the 1940s through coordinated salt-water reinjection that kept reservoir pressure high and pushed recovery efficiency above 75 percent, among the best of any giant field anywhere. That management is why a 1930 discovery still has producing wells nearly a century later, and why legacy East Texas royalties, though individually small, have paid for generations.
Most East Texas Field interests today are small, fragmented, and inherited — a decimal passed down through three or four generations, paying modest but persistent royalties from stripper production. Owners often face title work, unclaimed royalty balances, and division orders that no longer match the family tree. We buy legacy East Texas minerals and royalties across Gregg, Rusk, Upshur, Smith, and Cherokee counties, handle heirship and title work at our expense, and give you a firm written price for an interest that might otherwise cost more to administer than it pays.
County-level well data, production charts, and selling guides for the counties this field spans:
Yes, though far below its historic peak. Roughly 180 leases still report production to the Texas Railroad Commission, mostly at stripper-well rates sustained by the field’s famous water drive. Many royalty interests have paid continuously since the 1930s.
It was the largest conventional oil field in the lower 48 — over six billion barrels recovered — and its 1930s boom created modern oil regulation. Martial law, the Railroad Commission’s proration authority, and the price-stability framework that governed US oil for decades all trace directly to this field.
Usually yes, though legacy East Texas interests are typically modest — the value lies in the steady, water-drive-supported payment stream and in cleaning up title that families often let lapse. We make firm written offers on inherited East Texas interests of any size and handle the heirship documentation ourselves.
