It was permitted by Tidemark Exploration, Inc. and has since transferred to Chaparral Operating Inc. on the wellbore schedule.

Its 2 leases have reported 24.7K barrels of oil and 165K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
