Cavil Tyrena #11 (API 42-331-31770) is a plugged well in Milam County, plugged January 24, 2006, last operated by Rockdale Partners L.L.C..
The RRC has issued one drilling permit, issued April 6, 1983, permitted to 1,400 ft.
It was permitted by Enduro Oil Company Inc. and has since transferred to Rockdale Partners L.L.C. on the wellbore schedule.
Its lease has reported 720 barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Enduro Oil Company Inc.; the EWA schedule now lists a different operator.
