Koonce Farms 15 #1 (API 42-317-36205) is a well in Martin County operated by Diamondback E&P LLC, completed January 3, 2011 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended 3 times) between 2010 and 2016, 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 5 formation tops, including Spraberry, Strawn, Bend, Atoak.

Its lease has reported 146K barrels of oil and 296K mcf of gas since January 2011, 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.
