The RRC has issued one drilling permit, issued September 10, 1999, 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 T/Rustler, T/Yates, T/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.
