Warhorse (Clearfork UP.) Unit #506 (API 42-445-31495) is a well in Terry County operated by Extex Operating Company, completed July 14, 1992 and listed as shut in on the RRC schedule, shut in February 1, 2017.

The RRC has issued one drilling permit, issued October 8, 1987, permitted to 6,786 ft.

It was permitted by Texland-Rector & Schumacher and has since transferred to Extex Operating Company on the wellbore schedule.

Completion filings report 2 formation tops, including T. Upper Clearfork, T. Upper Clfk.

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.
