The RRC has issued one drilling permit, issued January 22, 1985, permitted to 5,000 ft.
It was permitted by Harkins & Company and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report one formation top, including Rincon North (4350').
Its lease has reported 8.79K barrels of oil and 9.09K mcf of gas since January 1993, last reporting in September 2014. The lease carries 5 wells, so these are lease totals, not this well alone.
