Mertins Karl A #21 (API 42-485-42286) is a well in Wichita County operated by G D Energy Corporation, completed October 10, 2020 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued January 10, 1991, permitted to 2,000 ft.
It was permitted by Campbell, Robert F. JR. and has since transferred to G D Energy Corporation on the wellbore schedule.

Its lease has reported 71.3K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
