Halsey 3 #103WD (API 42-317-40923) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed January 11, 2018.

The RRC has issued 2 drilling permits between 2017 and 2020, permitted to 10,500 ft.

It was permitted by Lario Oil & Gas Company 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 2 leases have reported 260K barrels of oil and 822K mcf of gas since February 2018, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
