Wth 20-8 D #243 (API 42-173-38844) is a horizontal well in Glasscock County operated by Diamondback E&P LLC, completed January 30, 2024 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 26, 2022, permitted to 10,330 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, Rustler, Yates, Seven Rivers.

Its lease has reported 906K barrels of oil and 4.29M mcf of gas since November 2022, last reporting in July 2026. The lease carries 3 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.
