The RRC has issued 2 drilling permits (amended once) between 1986 and 2000, permitted to 11,969 ft.
It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 20.4M barrels of oil and 7.45M mcf of gas since January 1993, last reporting in July 2026. The lease carries 687 wells, so these are lease totals, not this well alone.
