Plugged

Starr County · Los Olmos field · Vertical

Cook Vannie Trusts #D610 (API 42-427-31481) is a plugged well in Starr County, plugged June 17, 2008, last operated by Rns Oil CO..

The RRC has issued one drilling permit, issued November 19, 1980, permitted to 800 ft.

It was permitted by Duty Tool Company and has since transferred to Rns Oil CO. on the wellbore schedule.

Its lease has reported 12.3K barrels of oil and 18 mcf of gas since January 1993, last reporting in July 2026. The lease carries 59 wells, so these are lease totals, not this well alone.
