Dimmit County · Big Wells (San Miguel) field · Injection · Vertical
Big Wells /San Miguel/ Unit #2125 (API 42-127-31579) is a well in Dimmit County operated by Flint Oak Energy LLC, completed October 21, 2015 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 9, 1977, permitted to 5,600 ft.
It was permitted by Sun Exploration & Production CO. and has since transferred to Flint Oak Energy LLC on the wellbore schedule.
Completion filings report one formation top, including 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.
It holds an active disposal or injection permit, with 69.8K barrels injected in the 12 months reported through March 2026.
