Nail 127 J-12 #J22 (API 42-417-36878) is a well in Shackelford County operated by M & K Operating LLC, completed June 2, 1989 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued April 25, 1986, permitted to 1,750 ft.

It was permitted by One Madison Energy, Inc. and has since transferred to M & K Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Bluff Cr, Flippen, Hope.

Its lease has reported 5.17K barrels of oil and 86 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.
