Sibley 3-4 A #1WB (API 42-371-39373) is a horizontal well in Pecos County operated by Blue Arrow Operating LLC, completed October 17, 2019.
The RRC has issued one drilling permit (amended 3 times), issued November 20, 2015, permitted to 18,000 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 307K barrels of oil and 620K mcf of gas since October 2016, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
