Double Mountain A #4 (API 42-169-31679) is a plugged well in Garza County, plugged February 27, 2014, last operated by Chaparral Energy L.L.C..
The RRC has issued one drilling permit, issued October 28, 1981, permitted to 8,100 ft.
It was permitted by French, L. R., JR. and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Completion filings report 6 formation tops, including San Andres, Glorieta, Tubb, Strawn.
Its lease has reported 30.2K barrels of oil and 1.44K mcf of gas since January 1993, last reporting in January 2016. The lease carries 3 wells, so these are lease totals, not this well alone.
