Halsey 6 #104WA (API 42-317-41175) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed May 19, 2018.
The RRC has issued 2 drilling permits (amended once) 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 569K barrels of oil and 641K mcf of gas since May 2018, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
