Rio San Gabriel 28-29 Unit 1 #131 (API 42-329-44837) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed February 21, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 14, 2021, permitted to 9,061 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 3.45M barrels of oil and 11M mcf of gas since March 2019, last reporting in July 2026. The lease carries 15 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.
