Sts A - 1391 #12H (API 42-283-35222) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed July 9, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued November 6, 2014, permitted to 10,132 ft.
It was permitted by Hunt Oil Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Sparta, Queen City, Wilcox.
Its lease has reported 1.25M barrels of oil and 4.97M mcf of gas since December 2010, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
