Nail WC #4 (API 42-417-37407) is a plugged well in Shackelford County, plugged October 5, 2020, last operated by Petex.
The RRC has issued one drilling permit, issued July 26, 1990, permitted to 5,200 ft.
It was permitted by Jacobs, C. E., CO. and has since transferred to Petex on the wellbore schedule.
Completion filings report 5 formation tops, including B/Coleman Jct, Dothan, B/Breckenridge, Stran.
Its lease has reported 61.4K barrels of oil and 148K 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.
