Kloh #35 (API 42-227-34227) is a well in Howard County operated by Grayrock Energy II LLC, completed January 30, 1988 and listed as shut in on the RRC schedule, shut in February 1, 2014.

The RRC has issued one drilling permit, issued November 12, 1987, permitted to 2,600 ft.

It was permitted by Southland Royalty Company and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its 2 leases have reported 2.84M barrels of oil and 751 mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 168 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.
