Kloh #52 (API 42-173-33024) is a well in Glasscock County operated by Grayrock Energy II LLC, completed September 25, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued April 19, 2000, permitted to 2,600 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 an active disposal or injection permit, with 183K 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.
