Rio Lavaca 28-48 B #124 (API 42-329-46785) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed September 24, 2024 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued February 12, 2024, permitted to 8,641 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 15 formation tops, including Santa Rosa, Rustler, Yates, Queen.

Its lease has reported 1.04M barrels of oil and 4.12M mcf of gas since March 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.
