Duda #4 (API 42-433-32504) is a plugged well in Stonewall County, plugged June 3, 2014, last operated by Karper Oil & Gas Corporation.
The RRC has issued one drilling permit (amended once), issued May 8, 1989, permitted to 6,550 ft.
It was permitted by Santa FE Energy Oper. Part., LP and has since transferred to Karper Oil & Gas Corporation on the wellbore schedule.
Its lease has reported 203K barrels of oil and 57.7K mcf of gas since January 1993, last reporting in January 2015. The lease carries 2 wells, so these are lease totals, not this well alone.
