# Colorado Residents Owning Austin Chalk Mineral Interests in Texas

## TL;DR

Many Colorado residents own inherited Austin Chalk mineral or royalty interests from family members who lived or worked in central and south Texas during the 1970s Giddings boom. These interests span the Austin Chalk trend from the Giddings field through south Texas extensions, often including stacked-pay rights to the underlying Eagle Ford Shale. Owners can sell remotely through a streamlined process requiring only a Colorado notary, with proceeds typically wired the day the deed is recorded in Texas.

## Key Takeaways

- **Colorado residents commonly inherit Austin Chalk interests** from parents or grandparents who lived in central or south Texas during the 1970s–1990s oil booms.
- **Austin Chalk producing counties** include Brazos, Grimes, Burleson, Washington, Lee, Fayette (Giddings trend) and Karnes, DeWitt, Live Oak, McMullen, Webb, Dimmit, La Salle (south Texas extensions).
- **Many Austin Chalk leases include Eagle Ford Shale depths**, giving owners exposure to both the fractured carbonate Austin Chalk and the unconventional shale below.
- **Remote sales require no in-person meetings** — owners submit documentation by email, sign before a Colorado notary, and receive wire transfers upon recording in Texas.
- **Inherited interests typically receive stepped-up basis** to fair market value at the date of death, which can reduce taxable capital gains on near-term sales.
- **Four common interest types** include producing royalty, non-producing minerals, stacked-pay lease interest, and overriding royalty interest (ORRI).
- **Federal capital gains tax applies to mineral sales**, while Colorado state income tax treatment varies; consult a qualified Colorado CPA for individual guidance.

## Page Highlights

**Austin Chalk Ownership History**: The Austin Chalk has produced continuously since the 1960 Giddings discovery through multiple drilling eras — 1970s vertical wells, 1990s short-lateral horizontals, and 2018+ long-lateral renaissance. Many current Colorado owners inherited interests from relatives active during the original 1970s boom.

**Common Interest Types**: Colorado heirs typically hold producing royalty interest (fractional revenue share paid monthly), non-producing mineral interest (fee ownership in undrilled or shut-in sections), stacked-pay lease interest (covering both Austin Chalk and Eagle Ford), or overriding royalty interest (ORRI) carved from working interests.

**Geographic Footprint**: The Austin Chalk trend spans central Texas Giddings counties (Brazos, Grimes, Burleson, Washington, Lee, Fayette) and extends south through Karnes, DeWitt, Live Oak, McMullen, Webb, Dimmit, and La Salle counties. Most leases cover both Austin Chalk and underlying Eagle Ford Shale depths.

**Remote Sale Process**: Out-of-state owners submit county, legal description, and check stub information by email; receive a written offer; sign the mineral deed and purchase agreement before a Colorado notary; and receive wire transfer proceeds the day the deed is recorded with the Texas county clerk.

**Tax Considerations**: Federal capital gains tax applies to mineral sales, while Colorado state income tax treatment varies by individual circumstances. Inherited interests typically receive stepped-up basis to fair market value at the date of the decedent's death, potentially reducing taxable gain if sold soon after inheritance.
