Wilbanks 53 #1 (API 42-317-35477) is a well in Martin County operated by Diamondback E&P LLC, completed May 18, 2010 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 2008 and 2010, permitted to 10,775 ft.
It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Clear Fork, B/Clearfork, Spraberry, Dean.
Its 2 leases have reported 103K barrels of oil and 338K mcf of gas since December 2009, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
