Robinson A #1U (API 42-329-10034) is a well in Midland County operated by Diamondback E&P LLC, completed January 13, 2002 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2002 and 2013, permitted to 11,350 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 3.89K barrels of oil and 401K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
