Nail -D11- #4 (API 42-317-37545) is a plugged well in Martin County, plugged June 19, 2024, last operated by Oxyrock Operating LLC.

The RRC has issued one drilling permit, issued February 21, 2012, permitted to 11,900 ft.

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

Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.

Its lease has reported 440K barrels of oil and 1.58M mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 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.
