Clara Adams Unit 37 #1 (API 42-227-34972) is a well in Howard County operated by Diamondback E&P LLC, completed January 3, 1996.
The RRC has issued 2 drilling permits between 1995 and 2018, permitted to 9,200 ft.
It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Yates, Queen, San Andres, Spraberry.
Its 2 leases have reported 264K barrels of oil and 266K mcf of gas since January 1996, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
