Nail B-7 #1
Shackelford County · Cronk (Tannehill) field · NO Production · Vertical
Nail B-7 #1 (API 42-417-36618) is a well in Shackelford County operated by M & K Operating LLC, completed November 20, 1985 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued October 21, 1985, permitted to 990 ft.
It was permitted by Rampart Petroleum, Incorporated and has since transferred to M & K Operating LLC on the wellbore schedule.
Completion filings report one formation top, including L. Tannehill.
Its lease has reported 11.7K barrels of oil and 36 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
