Nail B-8 #4 (API 42-417-35899) is a well in Shackelford County operated by M & K Operating LLC, completed August 15, 1984 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued July 17, 1984, permitted to 900 ft.
It was permitted by Rampart Petroleum, Incorporated and has since transferred to M & K Operating LLC on the wellbore schedule.
Its lease has reported 687 barrels of oil and 36 mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
