Denman /Clark/ #5 I (API 42-227-33129) is a well in Howard County operated by Grayrock Energy II LLC, completed June 5, 2023 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 6, 1983, permitted to 2,900 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Its lease has reported 110K barrels of oil and 264 mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 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.
