The RRC has issued 2 drilling permits between 1982 and 1996, permitted to 9,400 ft.
It was permitted by Maralo, Inc. and has since transferred to Maralo LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its 2 leases have reported 43.5K barrels of oil and 35.9K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
