Holmes Millard #39W (API 42-371-32780) is a well in Pecos County operated by Clark Oil CO., completed December 13, 1979.
The RRC has issued one drilling permit, issued May 29, 1979, permitted to 1,918 ft.
It was permitted by Tenneco Oil CO. and has since transferred to Clark Oil CO. on the wellbore schedule.
Completion filings report one formation top, including Queen.
Its lease has reported 73K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 35 wells, so these are lease totals, not this well alone.
