North Penwell Unit #185W (API 42-135-36409) is a well in Ector County operated by Ring Energy Inc., completed June 2, 2010 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued January 22, 1991, permitted to 4,850 ft.

It was permitted by Phillips Petroleum Company and has since transferred to Ring Energy Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Yates, San Andres, Glorieta.

Its lease has reported 7.31M barrels of oil and 4.24M mcf of gas since January 1993, last reporting in July 2026. The lease carries 282 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 342K barrels injected in the 12 months reported through October 2025.
