Zavala County · Big Wells (San Miguel) field · Temp Abandoned · Horizontal · Directional
Big Wells (San Miguel) Unit #204 (API 42-507-32245) is a horizontal well in Zavala County operated by Flint Oak Energy LLC, completed January 17, 1995 and listed as temp abandoned on the RRC schedule, shut in December 1, 2016.
The RRC has issued 2 drilling permits (amended once) between 1989 and 1994, permitted to 8,785 ft.
It was permitted by Oryx Energy Company and has since transferred to Flint Oak Energy LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Taylor, San Miguel, Anacacho, Austin Chalk.
Its 2 leases have reported 830 barrels of oil and 304K 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.
