John Unit Waterflood #27 (API 42-169-33806) is a well in Garza County operated by Cml Exploration LLC, completed February 21, 2006 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 11, 2006, permitted to 5,150 ft.

It was permitted by Patterson Petroleum LP and has since transferred to Cml Exploration LLC on the wellbore schedule.

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

Its lease has reported 6.15M barrels of oil and 918K mcf of gas since September 1999, last reporting in July 2026. The lease carries 27 wells, so these are lease totals, not this well alone.
