Nail Ranch 151 #J25 (API 42-417-36905) is a well in Shackelford County operated by S2 Oil LLC (1), completed August 10, 1986 and listed as producing on the RRC schedule, shut in September 1, 2026.

The RRC has issued one drilling permit, issued May 30, 1986, permitted to 1,690 ft.

It was permitted by One Madison Energy, Inc. and has since transferred to S2 Oil LLC (1) on the wellbore schedule.

Completion filings report 2 formation tops, including Cook Sand, Hope Limestone.

Its lease has reported 5K barrels of oil and 75 mcf of gas since January 1993, last reporting volume in July 2025. The lease carries 4 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
