Mamba 6-35 Unit 2a #173 (API 42-317-44478) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed February 25, 2023 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued June 21, 2022, permitted to 8,239 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 3.78M barrels of oil and 10.2M mcf of gas since February 2023, 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.
