Quintanilla San Miguel #1 (API 42-311-33575) is a well in Mcmullen County operated by Gtg Operating LLC, completed April 3, 2000 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 1, 2000, permitted to 9,300 ft.
It was permitted by Welhausen Operating CO., Inc. and has since transferred to Gtg Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Olmos.
Its lease has reported 126K barrels of oil and 225K mcf of gas since April 2000, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
