Upton County · King Mountain (Devonian) field · Producing · Vertical
Mcclure W. W. A/C 1 #11 (API 42-461-32562) is a well in Upton County operated by Winn Operating LLC, completed July 1, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 21, 1986, permitted to 11,730 ft.
It was permitted by Sun Expl. & Prod. CO.-Midland and has since transferred to Winn Operating LLC on the wellbore schedule.
Completion filings report 16 formation tops, including Rustler, Yates, San Andres, Wolfcamp.
Its 2 leases have reported 368K barrels of oil and 6.76M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
