THE GREAT MILENKO UNIT 15-16
THE GREAT MILENKO UNIT 15-16 is a Texas oil lease in Reeves County, Railroad Commission district 08, operated by Callon Petroleum Operating Co. It has 6 wellbores on file with the Commission. Reported production runs from December 2021 to August 2026, totalling 1,037,283 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 $16.3M, with roughly $4.7M 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 6,697 barrels a month, about 1,116 per wellbore. Its strongest month on the record we hold was September 2022, at 104,694 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.
