Gonzales County · Eagleville (Eagle Ford-1) field · Vertical
Mahan #1SR (API 42-177-33478) is a well in Gonzales County operated by Auterra Operating LLC, completed September 27, 2014.
The RRC has issued one drilling permit, issued September 4, 2014, permitted to 7,995 ft.
It was permitted by Forest Oil Corporation and has since transferred to Auterra Operating LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Reklaw, Carrizo, Wilcox, Navarro.
Its 2 leases have reported 87.5K barrels of oil and 52K mcf of gas since July 2013, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
