Tinney Estate #5 (API 42-131-33964) is a plugged well in Duval County, plugged June 10, 2017, last operated by Chapco Inc..

The RRC has issued one drilling permit, issued October 26, 1979, permitted to 3,600 ft.

It was permitted by Davis & Forbes and has since transferred to Chapco Inc. on the wellbore schedule.

Its lease has reported 46.4K barrels of oil and 6 mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
