Blanco-Fullerton S #10S (API 42-003-38995) is a well in Andrews County operated by Extex Operating Company, completed September 18, 2002 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 22, 2002, permitted to 4,800 ft.

It was permitted by Blanco Oil CO. and has since transferred to Extex Operating Company on the wellbore schedule.

Completion filings report 3 formation tops, including Rustler, Yates, San Andres.

Its lease has reported 207K barrels of oil and 6.9K mcf of gas since March 1997, last reporting in July 2026. The lease carries 10 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.
