NIBLO "48"
NIBLO "48" is a Texas oil lease in King County, Railroad Commission district 8A, operated by Polk Petroleum, Inc. It has 5 wellbores on file with the Commission. Reported production runs from November 1994 to August 2026, totalling 302,394 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 $813K, with roughly $184K 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 259 barrels a month, about 52 per wellbore. Its strongest month on the record we hold was July 2017, at 347 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.
