Matlock #1 (API 42-237-37146) is a plugged well in Jack County, plugged January 26, 2018, last operated by Xstar Resources LLC.
The RRC has issued one drilling permit, issued April 8, 1986, permitted to 5,000 ft.
It was permitted by Catlin, Carl and has since transferred to Xstar Resources LLC on the wellbore schedule.
Completion filings report one formation top, including Conglomerate.
Its 2 leases have reported 9 barrels of oil and 65K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
