Stonewall County · Mullen Ranch (Ellenburger) field · Vertical
Duda #1 (API 42-433-32462) is a plugged well in Stonewall County, plugged June 26, 2014, last operated by Patton Exploration Inc..
The RRC has issued 2 drilling permits (amended once) between 1988 and 1991, permitted to 7,000 ft.
It was permitted by Santa FE Energy Oper. Part., LP and has since transferred to Patton Exploration Inc. on the wellbore schedule.
Its 2 leases have reported 267K barrels of oil and 87.8K mcf of gas since January 1993, last reporting in February 2016. The leases carry 5 wells, so these are lease totals, not this well alone.
