Super Unit #412 (API 42-181-00625) is a plugged well in Grayson County, plugged May 26, 2013, last operated by Flintlock Exploration LLC.

The RRC has issued one drilling permit, issued March 10, 1982, permitted to 3,637 ft.

It was permitted by Shell Oil Company and has since transferred to Flintlock Exploration LLC on the wellbore schedule.

Completion filings report one formation top, including Strawn.

Its 3 leases have reported 2.91M barrels of oil and 1.39M mcf of gas since January 1993, last reporting in July 2026. The leases carry 231 wells, so these are lease totals, not this well alone.
