Big Wells (San Miguel) Unit #5902 (API 42-507-32260) is a horizontal well in Zavala County operated by Flint Oak Energy LLC, completed September 25, 1994 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 1989 and 1994, permitted to 9,277 ft.

It was permitted by Oryx Energy Company and has since transferred to Flint Oak Energy LLC on the wellbore schedule.

Completion filings report 2 formation tops, including San Miguel, Austin Chalk.

Its 2 leases have reported 8.62K barrels of oil and 922K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
