Martin County · Spraberry (Trend Area) field · Shut IN  · Horizontal

Sundance Kid 43-7 Unit 2 #173JM (API 42-317-46406) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed August 20, 2025 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 5, 2024, 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 Clear Fork, Spraberry, Jo Mill, Dean.

Its lease has reported 1.93M barrels of oil and 2.59M mcf of gas since February 2025, last reporting in July 2026. The lease carries 13 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.
