Howard County · Howard Glasscock (Consolidated) field · Injection · Vertical
Clay H. R. #41 (API 42-227-33028) is a well in Howard County operated by Grayrock Energy II LLC, completed May 29, 1998 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits between 1983 and 1988, permitted to 3,303 ft.
It was permitted by Exxon Corp. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Seven Rivers, San Andres, Glorieta, Clear Fork.
Its 2 leases have reported 135K barrels of oil since January 1993, last reporting volume in April 2026. The leases carry 55 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 248 barrels injected in the 12 months reported through December 2025.
