Howard County · Howard Glasscock (Consolidated) field · Shut In · Vertical
Kloh #49 (API 42-227-35307) is a well in Howard County operated by Grayrock Energy II LLC, completed April 16, 1998 and listed as shut in on the RRC schedule, shut in March 1, 2026.
The RRC has issued one drilling permit, issued March 18, 1998, permitted to 2,600 ft.
It was permitted by Oryx Energy Company 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.
