Black Stone 1 #2H (API 42-371-39240) is a horizontal well in Pecos County operated by Blue Arrow Operating LLC, completed November 4, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended 3 times), issued September 10, 2014, permitted to 21,000 ft.
It was permitted by Diamondback E&P LLC and has since transferred to Blue Arrow Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Glorieta, Grayburg, O'Brien, Queen.
Its lease has reported 265K barrels of oil and 246K mcf of gas since November 2015, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
