# East Texas Oilfield Mineral Rights and Ownership

## TL;DR

The East Texas Oilfield, discovered in 1930 and known as the "Black Giant," is the largest single oil reserve in the contiguous United States, spanning five East Texas counties and having produced over 5.4 billion barrels from the Woodbine Sandstone. The field has been under continuous waterflood operations since 1965, providing stable royalty income to mineral owners whose ownership often traces back to original 1930s leases. The discovery's chaotic overproduction directly led to the modern Texas Railroad Commission regulatory framework that still governs U.S. oil and gas today.

## Key Takeaways

- The East Texas Oilfield was discovered in October 1930 by Dad Joiner's Daisy Bradford No. 3 well in Rusk County, Texas
- The field spans 140,000 acres across five counties: Rusk, Gregg, Smith, Upshur, and Cherokee, with cumulative production exceeding 5.4 billion barrels
- All production comes from a single Cretaceous-age formation — the Woodbine Sandstone — at depths of 3,200-3,800 feet with net pay thickness ranging from 30 to 100+ feet
- The field has operated under continuous waterflood since 1965, providing 60+ years of stable, predictable royalty income to mineral owners
- The 1930-1933 production chaos (prices below 10 cents/barrel) prompted creation of the Texas Railroad Commission pro-rationing system and the federal Connally Hot Oil Act of 1935
- Current mineral ownership is often fractional and spread across 4-5 generations of heirs whose ancestors signed original 1930-1932 leases
- The Woodbine produces through three historical mechanisms: primary depletion (1930-1942), gas reinjection (1942-1965), and waterflood (1965-present)

## Page Highlights

**The Black Giant Discovery**: Discovered in October 1930 by Dad Joiner in Rusk County, the East Texas Oilfield reached peak production of over 1 million barrels per day in 1933 and became the largest single oil reserve in the contiguous 48 states.

**Five Core Counties**: The field underlies Rusk County (Henderson), Gregg County (Kilgore and Longview), Smith County (Tyler), Upshur County (Gladewater), and Cherokee County (Rusk), with Gregg County containing the densest concentration of producing wells.

**Woodbine Formation**: The entire field produces from the Upper Cretaceous Woodbine Sandstone, which pinches out against the Sabine Uplift to create a stratigraphic trap holding the massive oil reserve.

**Historical Regulatory Impact**: The 1930-1933 overproduction crisis forced oil prices below 10 cents per barrel and directly led to establishment of the modern Texas Railroad Commission pro-rationing system and the 1935 federal Connally Hot Oil Act.

**Waterflood Operations**: The field has been under continuous waterflood for 60+ years (since 1965), providing stable and predictable long-term royalty income to mineral owners.

**Generational Ownership Complexity**: Mineral ownership in the East Texas Oilfield typically extends across 4-5 generations of heirs whose ancestors signed original leases between 1930-1932.
