Rhea 1-6 Unit 1 #123 (API 42-317-42863) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed December 22, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 22, 2020, 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, Queen, Grayburg.

Its lease has reported 2.66M barrels of oil and 4.71M mcf of gas since February 2020, 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.
