It was permitted by Marathon Oil Company and has since transferred to Black River Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Seven Rivers, Queen, Grayburg, San Andres.
Its lease has reported 115K barrels of oil since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
