KARNES CITY NW UNIT
KARNES CITY NW UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 6 wellbores on file with the Commission. Reported production runs from February 2015 to August 2026, totalling 2,115,923 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 $4.6M, with roughly $2.0M 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 3,987 barrels a month, about 665 per wellbore. Its strongest month on the record we hold was July 2017, at 207,347 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.
