Super Unit #400 (API 42-181-01867) is a well in Grayson County operated by Flintlock Exploration LLC, completed July 17, 1981 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 25, 1981, permitted to 6,965 ft.
It was permitted by Shell Oil Company and has since transferred to Flintlock Exploration LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Strawn, Barnes, S Sandstone, U Sandstone.
Its 2 leases have reported 2.89M barrels of oil and 1.37M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 214 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Shell Oil Company; the EWA schedule now lists a different operator.
