Dimmit County · Big Wells (San Miguel) field · Vertical
Big Wells /San Miguel/ Unit #5455 (API 42-127-32207) is a plugged well in Dimmit County, plugged August 18, 1993, last operated by Flint Oak Energy LLC.
The RRC has issued one drilling permit, issued June 4, 1981, permitted to 5,770 ft.
It was permitted by Sun Expl. & Prod. CO.-Houston 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 volume in April 2026. The lease carries 337 wells, so these are lease totals, not this well alone.
