The RRC has issued one drilling permit, issued October 12, 2000, permitted to 5,100 ft.
It was permitted by Walsh Petroleum, Inc. and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 383K barrels of oil and 355K mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
