Finishing Nail 2528b #3MS (API 42-317-40918) is a horizontal well in Martin County operated by Oxyrock Operating LLC, completed October 2, 2025 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 18, 2017, permitted to 8,700 ft.

It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Yates, Grayburg, San Andres, Clear Fork.

Its lease has reported 831K barrels of oil and 2.05M mcf of gas since April 2018, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
