A guide to East Texas Oilfield mineral rights in Gregg County (Kilgore (heart of the field) and Longview) — the densest concentration of producing wells of the Black Giant.
Get a Free Mineral ValuationGregg County (Kilgore (heart of the field) and Longview) sits in the densest concentration of producing wells 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.
Gregg County is the operational heart of the East Texas Oilfield. Kilgore — the "City of Stars" with its iconic World's Richest Acre downtown — sits at the field's most productive area. The county hosts more East Texas Oilfield wells than any other county and remains the focus of waterflood maintenance investment.
Woodbine Sandstone — Cretaceous-age primary producing formation; depths typically 3,200-3,800 ft TVD across Gregg 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
Gregg 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 Gregg 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 Gregg County interests have been continuously producing since the 1930s, with current ownership spread across multiple generations of heirs.
Gregg 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 Gregg County interests can sell entirely remotely.
