Block 9 Fuhrman-Mascho Unit #158 (API 42-003-39359) is a well in Andrews County operated by Winn Operating LLC, completed November 23, 2004 and listed as shut in on the RRC schedule, shut in June 1, 2026.

The RRC has issued one drilling permit, issued September 16, 2004, permitted to 4,785 ft.

It was permitted by Thompson, J. Cleo and has since transferred to Winn Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Queen, Grayburg, San Andres.

Its lease has reported 2.05M barrels of oil and 551K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 160 wells, so these are lease totals, not this well alone.

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