Millard -C- #27 (API 42-135-42275) is a well in Ector County operated by Ring Energy Inc., completed May 22, 2015.

The RRC has issued 2 drilling permits between 2013 and 2019, permitted to 9,300 ft.

It was permitted by Founders Oil & Gas Operating,LLC and has since transferred to Ring Energy Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Clear Fork, Wichita-Albany, Wolfcamp, Devonian.

Its 2 leases have reported 782K barrels of oil and 1.46M mcf of gas since January 1993, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
