Duval County Ranch CO. -T- #23 (API 42-131-39120) is a well in Duval County operated by Production Resources Inc., completed October 23, 2008 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 9, 2008, permitted to 1,400 ft.
It was permitted by Gulftex Energy, LLC and has since transferred to Production Resources Inc. on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its lease has reported 21.8K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
