BRYSCH JONAS UNIT
BRYSCH JONAS UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 9 wellbores on file with the Commission. Reported production runs from August 2011 to August 2026, totalling 1,689,600 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 $1.5M, with roughly $630K 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 1,665 barrels a month, about 185 per wellbore. Its strongest month on the record we hold was December 2016, at 109,029 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.
