Nail Ranch 152a #1 (API 42-417-36377) is a well in Shackelford County operated by S2 Oil LLC (1), completed July 26, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 20, 1985, permitted to 1,999 ft.
It was permitted by Aspen Oil & Gas and has since transferred to S2 Oil LLC (1) on the wellbore schedule.
Completion filings report 3 formation tops, including Sdi Creek, Flippen Lime, Breckenridge Lime.
Its lease has reported 10.1K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
