Warhorse (Clearfork UP.) Unit #1 (API 42-445-30823) is a plugged well in Terry County, plugged July 28, 1994, last operated by Extex Operating Company.
The RRC has issued one drilling permit, issued February 13, 1980, permitted to 6,900 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report one formation top, including Clear Fork.
Its lease has reported 694K barrels of oil and 122K mcf of gas since January 1993, last reporting in July 2026. The lease carries 55 wells, so these are lease totals, not this well alone.
