McMullen County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Mahoney Unit #2H (API 42-311-35165) is a horizontal well in Mcmullen County operated by Enerquest Operating L.L.C., completed September 25, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 25, 2012, permitted to 16,800 ft.
It was permitted by Marathon Oil EF LLC and has since transferred to Enerquest Operating L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 184K barrels of oil and 225K mcf of gas since January 2013, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
