Nacogdoches County · Nacogdoches field · Shut IN · Vertical
Mast A. T. C #11C (API 42-347-31427) is a well in Nacogdoches County operated by Hereford J. A. Industries Inc., completed August 21, 1985 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued June 19, 1985, permitted to 1,000 ft.
It was permitted by Smith Oil & Gas, Inc. and has since transferred to Hereford J. A. Industries Inc. on the wellbore schedule.
Its lease has reported 110 barrels of oil and 126 mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
