# Brazos County Austin Chalk Mineral Rights and Production Activity

**TL;DR:** Brazos County (Bryan/College Station area) lies in the northern extension of the Austin Chalk Giddings trend, with EOG Resources leading modern horizontal drilling activity. Most leases cover both Austin Chalk (7,000–10,000 ft TVD) and underlying Eagle Ford Shale depths, creating stacked-pay valuation considerations. The county has seen horizontal redevelopment since approximately 2018.

## Key Takeaways

- **Brazos County sits in the northern Giddings extension** of the Austin Chalk trend, with commercial production dating to the 1960s and horizontal redevelopment beginning around 2018
- **EOG Resources dominates modern drilling**, with significant long-lateral horizontal positions in both Austin Chalk and Eagle Ford formations
- **Stacked-pay leases are common** — many Brazos County mineral leases cover both Austin Chalk (primary target) and underlying Eagle Ford Shale depths
- **Producing depths typically range 7,000–10,000 ft TVD** across the county, with Austin Chalk as the primary producing formation
- **Surface complications are minimal** — production occurs mainly north and east of the Bryan/College Station urban core, with well-coordinated land use
- **RRC Form W-1 and P-12 filings** signal imminent drilling and pooled unit formation; monitoring these permits helps mineral owners anticipate activity
- **Out-of-state mineral ownership is common** in Brazos County, with many interests inherited across multiple generations and states
- **Valuation should account for both zones** when leases cover stacked pay, including active production, unproduced optionality, and zone-specific lease terms

## Page Highlights

**County Position in Austin Chalk Trend:** Brazos County occupies the northern extension of the Giddings Austin Chalk trend, hosting Texas A&M University and Bryan/College Station but with most production activity concentrated north and east of the urban area.

**Producing Formations:** Austin Chalk serves as the primary producing formation (Upper Cretaceous fractured carbonate at 7,000–10,000 ft TVD), with Eagle Ford Shale underlying it and selective Buda Limestone production above in some areas.

**Operator Landscape:** EOG Resources leads modern long-lateral horizontal drilling in both Austin Chalk and Eagle Ford; other active operators include Crownquest Operating and Validus Energy.

**Texas RRC Permit System:** Form W-1 (drilling permit) and Form P-12 (Pooled Unit Designation) are the two critical permit types for mineral owners to monitor; both signal upcoming drilling activity on specific sections.

**Selling Considerations:** Buckhead Energy purchases mineral and royalty interests across Brazos County regardless of production status (modern horizontal, legacy vertical, or held-by-production under lease).

**Stacked-Pay Valuation:** Many Brazos County leases span both Austin Chalk and Eagle Ford depths, requiring valuation that accounts for the actively producing zone, unproduced zone optionality, and any formation-specific lease language.
