Cornell Unit #6365 (API 42-501-10038) is a plugged well in Yoakum County, plugged March 31, 1992, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued March 3, 1978, permitted to 8,597 ft.
It was permitted by Cornell Oil CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its lease has reported 20.3M barrels of oil and 35.4M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 268 wells, so these are lease totals, not this well alone.
