# Washington County Austin Chalk Mineral Rights

## TL;DR

Washington County sits in the central Giddings core of the Austin Chalk trend and has seen renewed drilling activity since 2018 with modern long-lateral horizontal wells. EOG Resources is the dominant operator, with Bayswater Exploration also active. Many mineral leases in the county cover both Austin Chalk and Eagle Ford Shale depths, creating stacked-pay optionality for owners.

## Key Takeaways

- **Washington County is positioned in the central Giddings core**, one of the most historically productive areas of the Austin Chalk trend with commercial development dating to the 1960s
- **Long-lateral horizontal redevelopment began around 2018** and has been particularly active in the central and northern parts of the county
- **EOG Resources operates most of the modern long-lateral activity** in Washington County, with Bayswater Exploration maintaining a secondary position
- **Austin Chalk is the primary producing formation** at depths of 7,000-10,000 feet true vertical depth (TVD) across the county
- **Many Washington County leases cover both Austin Chalk and Eagle Ford Shale depths**, requiring valuations to account for both the actively producing zone and unproduced zone optionality
- **Out-of-state mineral ownership is common** due to inherited interests passing through multiple generations of heirs
- **Texas Railroad Commission Form W-1 (drilling permit) and Form P-12 (Pooled Unit Designation) are the key permit types** mineral owners should monitor for activity on their tracts
- **Brenham serves as the county seat** and historic center of the Texas dairy industry alongside substantial oil and gas production

## Page Highlights

**Washington County Overview**: Washington County is located in the central Giddings core of the Austin Chalk trend, with commercial production history dating to the 1960s. Modern long-lateral horizontal wells drilled from approximately 2018 onward have revitalized many sections, particularly in central and northern parts of the county.

**Producing Formations**: The Austin Chalk is the primary producing formation at 7,000-10,000 feet TVD. The Eagle Ford Shale sits stratigraphically below the Austin Chalk and is covered by many Washington County leases. The Buda Limestone sits above the Austin Chalk with selective production in some areas.

**Operator Activity**: EOG Resources maintains a core operating position with significant modern long-lateral activity. Bayswater Exploration and other operators also hold positions in the county.

**Regulatory Monitoring**: Mineral owners can track drilling activity through Texas Railroad Commission permits — specifically Form W-1 (drilling permit applications) and Form P-12 (Pooled Unit Designations for multi-tract horizontal wells).

**Stacked-Pay Considerations**: Many Washington County leases cover both Austin Chalk and Eagle Ford depths. Mineral owners should ensure valuations account for both the actively producing zone and any unproduced zone optionality, as well as zone-specific lease terms.

**Selling Considerations**: Buckhead Energy purchases mineral rights and royalty interests across Washington County regardless of production status — whether currently producing under modern long-laterals, producing from original 1970s vertical wells, or held by production under unproduced leases. Out-of-state heirs who inherited Washington County mineral interests are common sellers.
