Mallet Unit #1111 (API 42-079-30269) is a well in Cochran County operated by Hilcorp Energy Company, completed October 17, 2007 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 21, 2007, permitted to 5,115 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its lease has reported 25M barrels of oil and 40.1M mcf of gas since January 1993, last reporting in July 2026. The lease carries 352 wells, so these are lease totals, not this well alone.
