Dcr-State 366/76/64/54 #12 (API 42-131-37856) is a plugged well in Duval County, plugged May 15, 2015, last operated by Killam Oil CO. Ltd..

The RRC has issued one drilling permit, issued December 22, 1993, permitted to 1,600 ft.

It was permitted by Sonat Exploration CO. - Houston and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.

Completion filings report one formation top, including Cole.

Its lease has reported 655K barrels of oil and 12.3K mcf of gas since January 1993, last reporting in July 2026. The lease carries 26 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
