Koonce South 46-3 Unit 1 #122 (API 42-173-38196) is a horizontal well in Glasscock County operated by Diamondback E&P LLC, completed April 21, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 8, 2019, 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 Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 2.63M barrels of oil and 13.6M mcf of gas since November 2018, last reporting in July 2026. The lease carries 9 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.
