RUMAGE
RUMAGE is a Texas oil lease in Jack County, Railroad Commission district 09, operated by White Knight Production LLC. It has 4 wellbores on file with the Commission. Reported production runs from August 2018 to August 2026, totalling 488,817 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 $6.1M, with roughly $1.5M 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 2,096 barrels a month, about 524 per wellbore. Its strongest month on the record we hold was August 2019, at 15,095 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.
