Ackerly /Dean/ Field Unit #502 (API 42-115-31566) is a plugged well in Dawson County, plugged January 14, 2016, last operated by Mule Kick Operating LLC.
The RRC has issued one drilling permit, issued July 29, 1981, permitted to 8,850 ft.
It was permitted by Superior Oil Company, The and has since transferred to Mule Kick Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Dean.
Its lease has reported 4.63M barrels of oil and 2.73M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 119 wells, so these are lease totals, not this well alone.
