Get a Free Mineral ValuationUpshur County (Gladewater) sits in the northern extension of the East Texas Oilfield. The county has been producing oil from the Cretaceous Woodbine Sandstone since the field's discovery era and remains an active waterflood producer today.
Upshur County hosts the northern extension of the East Texas Oilfield. The Lou Della Crim well in December 1930 — which extended the field 12 miles north of the original Daisy Bradford discovery — was drilled in the Gregg/Upshur county region. Upshur County hosts significant waterflood production and continues to deliver predictable royalty income to mineral owners.
Woodbine Sandstone — Cretaceous-age primary producing formation; depths typically 3,200-3,800 ft TVD across Upshur County; on continuous waterflood since the 1960s
Eagle Ford Shale — sits stratigraphically below the Woodbine; selective horizontal exploration in some sections; East Texas Eagle Ford is a separate play from the south Texas Eagle Ford
Upshur County is dominated by long-tenured private waterflood operators running East Texas Oilfield units. Major operator categories include the field's traditional waterflood operators (Crawford Oil & Gas, Texas Petroleum Investment, Hilcorp, Riley Exploration), small private stripper-well operators, and selective horizontal Eagle Ford explorers.

Mineral interests in Upshur County typically deliver small monthly royalty checks for many decades. Per-well rates are typically 1-15 BOPD with high water cuts; decline rates are 2-6% per year on long-life waterflood wells. Many Upshur County interests have been continuously producing since the 1930s, with current ownership spread across multiple generations of heirs.
Upshur County interests are well-suited to mineral owners considering a sale because the field's long, predictable waterflood production makes valuations relatively straightforward. The DCF framework prices in the remaining waterflood reserve life plus any prospective Eagle Ford optionality. Out-of-state heirs of Upshur County interests can sell entirely remotely.
