Clay H. R. #57 (API 42-227-34369) is a well in Howard County operated by Grayrock Energy II LLC, completed June 23, 1995 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued July 19, 1988, permitted to 3,368 ft.

It was permitted by Exxon Corp. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

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 650 barrels injected in the 12 months reported through December 2025.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
