Anaconda 5-4 Unit 2 #183 (API 42-317-43727) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed June 11, 2022 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued August 13, 2021, permitted to 11,000 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 5.2M barrels of oil and 13.4M mcf of gas since March 2022, last reporting in July 2026. The lease carries 16 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.
