Mcnallen H. R. Clay #12 (API 42-227-10155) is a well in Howard County operated by Quantum Resources Management LLC, completed January 24, 2001.
The RRC has issued one drilling permit, issued August 3, 2000, permitted to 3,350 ft.
It was permitted by Westport Oil And Gas Company Inc and has since transferred to Quantum Resources Management LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its 4 leases have reported 70K barrels of oil and 594 mcf of gas since January 1993, last reporting in July 2026. The leases carry 35 wells, so these are lease totals, not this well alone.
