Koonce 39 #2 (API 42-173-33252) is a well in Glasscock County operated by Diamondback E&P LLC, completed January 19, 2007 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2006 and 2018, permitted to 12,000 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Spraberry, Jo Mill, Dean, Strawn.

Its lease has reported 126K barrels of oil and 256K mcf of gas since January 2003, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
