Mccain L.W. #5 (API 42-013-33167) is a well in Atascosa County operated by Old Chief Oil LLC, completed December 27, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 18, 1985, permitted to 1,540 ft.
It was permitted by Grindl, Anthony R. and has since transferred to Old Chief Oil LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Escondido, Lit, Olmos.
Its lease has reported 6.35K barrels of oil and 540 mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Grindl, Anthony R.; the EWA schedule now lists a different operator.
