Mackey L. L. #4 (API 42-183-30858) is a well in Gregg County operated by Dallas Production Company LLC, completed November 12, 2013 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1991 and 2012, permitted to 10,820 ft.
It was permitted by Dallas Production, Inc. and has since transferred to Dallas Production Company LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Rodess, Rodessa, Pettit, Travis Peak.
Its 2 leases have reported 60.9K barrels of oil and 1.71M mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
