Rio Concho 34-46 B #123 (API 42-329-43686) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed February 20, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 27, 2019, permitted to 10,500 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 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 757K barrels of oil and 3.73M mcf of gas since February 2020, 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.
