CUMBIE
CUMBIE is a Texas oil lease in Stonewall County, Railroad Commission district 7B, operated by Nosivad Oil, Inc. It has 2 wellbores on file with the Commission. Reported production runs from August 1995 to August 2026, totalling 27,191 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 $4K, with roughly $754 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 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was August 2018, at 97 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
