South Phoenix (Grayburg) Unit #27 (API 42-317-33875) is a plugged well in Martin County, plugged March 13, 2018, last operated by Cazador Operating LLC.
The RRC has issued one drilling permit, issued June 19, 1991, permitted to 4,100 ft.
It was permitted by Beach Exploration, Inc. and has since transferred to Cazador Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
Its lease has reported 214K barrels of oil and 147 mcf of gas since January 1993, last reporting in July 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
