Not one formation; the well must be completed in one of them, and no target formation is stated.

Clay H. R. #51 (API 42-227-34362) is a well in Howard County operated by Grayrock Energy II LLC, completed November 12, 1988 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 11, 1988, permitted to 3,385 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 1.01M barrels of oil and 68.8K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 61 wells, so these are lease totals, not this well alone.

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