Koonce West 46-34 Unit 1 #273 (API 42-173-38563) is a horizontal well in Glasscock County operated by Diamondback E&P LLC, completed September 19, 2022 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 24, 2021, permitted to 10,760 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 13 formation tops, including Santa Rosa, Rustler, Yates, Seven Rivers.

Its lease has reported 4.05M barrels of oil and 12.8M mcf of gas since September 2022, last reporting in July 2026. The lease carries 11 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.
