Menchaca #4 (API 42-325-34167) is a well in Medina County operated by 1859 Operating LLC, completed July 1, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 5, 2014, permitted to 1,500 ft.
It was permitted by Premier Minerals, Inc. and has since transferred to 1859 Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Escondido, Olmos, Anacacho, Buda.
Its lease has reported 9.79K barrels of oil since March 2014, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
