Chest Thumper 1-5 Unit 1 #143 (API 42-317-45291) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed August 1, 2023 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued June 16, 2023, permitted to 9,264 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 Cisco, Dean, Grayburg, Pennsylvanian.

Its lease has reported 3.08M barrels of oil and 6.28M mcf of gas since August 2023, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
