The RRC has issued one drilling permit, issued June 26, 1985, permitted to 8,600 ft.
It was permitted by Amoco Production CO.-Andrews and has since transferred to Octane Energy Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Rustler, Grayburg, Devonian, Silurian (undifferentiated).
Its lease has reported 476K barrels of oil and 303K mcf of gas since January 1993, last reporting in July 2026. The lease carries 25 wells, so these are lease totals, not this well alone.
