Production

This well does not appear on its own in the NDIC Monthly Production Reports for Jan 2003 to Aug 2026, which list every well that reported in a month. Before May 2015 a well in a unitized pool was listed only inside its unit's total, so such a well does not appear on its own in those years either.
