Breedlove 91 #9 (API 42-317-34478) is a well in Martin County operated by Diamondback E&P LLC, completed June 10, 2015 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2004 and 2015, permitted to 12,197 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its 2 leases have reported 112K barrels of oil and 26.4K mcf of gas since November 2004, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
