It was permitted by Navidad Resources, LLC and has since transferred to Sem Operating Company LLC on the wellbore schedule.

Its 3 leases have reported 39.2K barrels of oil and 159K mcf of gas since August 2010, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
