Rio Brazos 26-15 Unit 1 #124 (API 42-329-45382) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed December 29, 2022 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued January 18, 2022, permitted to 10,300 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 11 formation tops, including Santa Rosa, Rustler, Yates, Seven Rivers.

Its lease has reported 4.8M barrels of oil and 14.5M mcf of gas since May 2022, last reporting in July 2026. The lease carries 14 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.
