PFEIFER UNIT
PFEIFER UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 4 wellbores on file with the Commission. Reported production runs from April 2011 to August 2026, totalling 683,299 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 $161K, with roughly $67K 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 310 barrels a month, about 77 per wellbore. Its strongest month on the record we hold was August 2016, at 3,845 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
