Frymire Waterflood Unit #12 (API 42-353-00273) is a plugged well in Nolan County, plugged November 6, 2001, last operated by Grayrock Energy II LLC.

The RRC has issued 2 drilling permits between 1977 and 2001, permitted to 5,345 ft.

It was permitted by Cockrell Production CO., Inc. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Its 2 leases have reported 431K barrels of oil and 99.9K mcf of gas since January 1993, last reporting in July 2026. The leases carry 24 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.
