McMullen County · A.W.P. (Olmos) field · Shut In · Vertical
Horton -M- #1 (API 42-311-32035) is a well in Mcmullen County operated by Gtg Operating LLC, completed April 14, 1984 and listed as shut in on the RRC schedule, shut in April 1, 2019.
The RRC has issued one drilling permit, issued March 9, 1984, permitted to 9,366 ft.
It was permitted by Tana Oil & Gas Corp. and has since transferred to Gtg Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Olmos.
Its lease has reported 132K barrels of oil and 1.03M mcf of gas since January 1993, last reporting volume in February 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
