The RRC has issued one drilling permit (amended once), issued June 21, 2007, permitted to 4,900 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Seven Rivers, Queen, Grayburg, San Andres.
Its lease has reported 321K barrels of oil and 2.05M mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
