Welch SE (Spraberry) Unit #1-11 (API 42-115-31693) is a plugged well in Dawson County, plugged August 30, 1996, last operated by Libertad Operating LLC.
The RRC has issued one drilling permit, issued June 18, 1982, permitted to 7,850 ft.
It was permitted by Bta Oil Producers and has since transferred to Libertad Operating LLC on the wellbore schedule.
Its lease has reported 581K barrels of oil and 54.2K mcf of gas since January 1993, last reporting in July 2026. The lease carries 25 wells, so these are lease totals, not this well alone.
