Howard County · Spraberry (Trend Area) field · Horizontal
Black Pearl 11-14 Unit 1 #271 (API 42-227-40379) is a horizontal well in Howard County operated by Diamondback E&P LLC, completed November 30, 2019.
The RRC has issued one drilling permit, issued September 18, 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 10 formation tops, including Yates, Seven Rivers, San Andres, Glorieta.
Its 2 leases have reported 4.11M barrels of oil and 20.5M mcf of gas since June 2019, last reporting in July 2026. The leases carry 20 wells, so these are lease totals, not this well alone.
