ZR UNIT "C"

Reported production runs from August 1999 to August 2026, totalling 16,147 barrels. The lease is shut in. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values the whole lease — a 100% undivided interest — at about $15K, with roughly $3K expected over the next twelve months.
