The RRC has issued one drilling permit, issued September 1, 1989, permitted to 5,798 ft.
It was permitted by Oryx Energy Company and has since transferred to Flint Oak Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Escondido, Olmos, San Miguel.
Its lease has reported 250K barrels of oil and 20.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 47 wells, so these are lease totals, not this well alone.
