ZISSOU
ZISSOU is a Texas oil lease in Howard County, Railroad Commission district 08, operated by SM Energy Company. It has 2 wellbores on file with the Commission. Reported production runs from June 2018 to August 2026, totalling 672,427 barrels. The lease is currently producing. 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 $4.3M, with roughly $1.3M expected over the next twelve months. An individual royalty owner receives their own decimal interest times that figure. Over the last twelve months on file it averaged 2,131 barrels a month, about 1,065 per wellbore. Its strongest month on the record we hold was July 2018, at 64,185 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% of what they went on to produce, and that measured error is the range shown on the page rather than a confidence of our own devising.
