Big Wells /San Miguel/ Unit #2135 (API 42-127-33641) is a well in Dimmit County operated by Flint Oak Energy LLC, completed April 12, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 18, 2009, permitted to 5,530 ft.
It was permitted by Texas American Resources Company and has since transferred to Flint Oak Energy LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Olmos, San Miguel.
Its lease has reported 3.1M barrels of oil and 998K mcf of gas since January 1993, last reporting in July 2026. The lease carries 337 wells, so these are lease totals, not this well alone.
