Midland County · Spraberry (Trend Area) field · Producing · Horizontal
Brethern #1 (API 42-329-34541) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed June 19, 2009 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits (amended 3 times) between 2001 and 2013, permitted to 11,684 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 7 formation tops, including Yates, Spraberry, Dean, Wolfcamp.
Its 2 leases have reported 67.5K barrels of oil and 255K mcf of gas since June 2002, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
