Warhorse (Clearfork UP.) Unit #2 (API 42-445-00271) is a well in Terry County operated by Extex Operating Company, completed November 27, 1987 and listed as shut in on the RRC schedule, shut in April 1, 2023.

The RRC has issued one drilling permit, issued August 25, 1978, permitted to 6,992 ft.

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

Completion filings report 3 formation tops, including Rustler, Glorieta, Clear Fork.

Its lease has reported 694K barrels of oil and 122K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 55 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
