Duval County · Colmena field · Shut In · Vertical
Duval CO. Ranch CO.-State -L- #L-34 (API 42-131-35186) is a well in Duval County operated by Caribbean Energy LLC II, completed January 5, 1982 and listed as shut in on the RRC schedule, shut in January 1, 2018.
The RRC has issued one drilling permit, issued April 3, 1981, permitted to 1,452 ft.
It was permitted by Speedman Oil CO. and has since transferred to Caribbean Energy LLC II on the wellbore schedule.
Its lease has reported 133K barrels of oil and 20 mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 36 wells, so these are lease totals, not this well alone.
