Black Cobra 1-2 Unit B #66H (API 42-389-36308) is a horizontal well in Reeves County operated by Noble Energy Inc, completed July 27, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 6, 2017, permitted to 13,000 ft.
It was permitted by Nbl Permian LLC and has since transferred to Noble Energy Inc on the wellbore schedule.
Completion filings report 8 formation tops, including Castile, Delaware, Bell Canyon, Cherry Canyon.
Its lease has reported 599K barrels of oil and 1.59M mcf of gas since July 2018, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
