The RRC has issued 2 drilling permits between 1977 and 2001, permitted to 5,000 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to White Rock Oil & Gas LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 9.43M barrels of oil and 1.77M mcf of gas since January 1993, last reporting in July 2026. The lease carries 293 wells, so these are lease totals, not this well alone.
