Nail A #101 (API 42-417-37668) is a plugged well in Shackelford County, plugged October 18, 2001, last operated by Marjac Oil Company Inc..
The RRC has issued one drilling permit, issued March 25, 1993, permitted to 1,999 ft.
It was permitted by Thornton, Michael D. and has since transferred to Marjac Oil Company Inc. on the wellbore schedule.
Completion filings report one formation top, including Fry.
Its lease has reported 156 barrels of oil and 12 mcf of gas since June 1993, last reporting in December 2001. The lease carries 2 wells, so these are lease totals, not this well alone.

Permitted by Thornton, Michael D.; the EWA schedule now lists a different operator.
