It was permitted by Rust Oil Corp. and has since transferred to Hillin-Simon Oil Company on the wellbore schedule.

Its lease has reported 398K barrels of oil and 542K mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
