Kloh #57 (API 42-173-33027) is a well in Glasscock County operated by Grayrock Energy II LLC, completed April 29, 2016 and listed as shut in on the RRC schedule, shut in March 1, 2016.

The RRC has issued 2 drilling permits between 1998 and 2000, permitted to 2,553 ft.

It was permitted by Kerr-Mcgee Oil & Gas Onshore LLC and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report one formation top, including San Andres.

Its 2 leases have reported 2.84M barrels of oil and 751 mcf of gas since January 1993, last reporting in July 2026. The leases carry 168 wells, so these are lease totals, not this well alone.

It holds 2 active disposal or injection permits.
