Williams N. M. #8 (API 42-445-31397) is a well in Terry County operated by Shinnery Oil Company Inc., completed October 9, 1985 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 9, 1985, permitted to 6,800 ft.

It was permitted by Markay Oil & Gas Company and has since transferred to Shinnery Oil Company Inc. on the wellbore schedule.

Completion filings report 4 formation tops, including Anhydrite, San Andres, Glorieta, Clear Fork.

Its lease has reported 177K barrels of oil and 93.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 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.
