Quintanilla Smef #1H (API 42-311-35159) is a horizontal well in Mcmullen County operated by Silverbow Resources Oper LLC, completed January 5, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued October 12, 2012, permitted to 10,765 ft.

It was permitted by Sea Eagle Ford, LLC and has since transferred to Silverbow Resources Oper LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 1.39M barrels of oil and 3.26M mcf of gas since January 2013, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
