Wth 22-15 B #221 (API 42-329-43702) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed April 28, 2020 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued October 31, 2019, permitted to 11,000 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 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 470K barrels of oil and 2.44M mcf of gas since April 2020, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
