Welch SE (Spraberry) Unit #1 (API 42-115-31224) is a plugged well in Dawson County, plugged December 1, 2008, last operated by Libertad Operating LLC.
The RRC has issued 2 drilling permits in 1978, permitted to 7,850 ft.
It was permitted by Bta Oil Producers and has since transferred to Libertad Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Clear Fork.
Its lease has reported 581K barrels of oil and 54.2K mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 25 wells, so these are lease totals, not this well alone.
