It was permitted by Seagull Operating CO. Inc. and has since transferred to Koko Skadi LLC on the wellbore schedule.

Its lease has reported 28.7K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
