Branch 46 #1 (API 42-173-33069) is a well in Glasscock County operated by Diamondback E&P LLC, completed September 22, 2001 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 2001 and 2018, permitted to 10,520 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 Spraberry, Upper Sparaberry, Lower Sprabeerry, Dean.
Its 2 leases have reported 86.9K barrels of oil and 112K mcf of gas since October 2001, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
