NIX 31
NIX 31 is a Texas oil lease in Dawson County, Railroad Commission district 8A, operated by R K Petroleum Corp. It has 2 wellbores on file with the Commission. Reported production runs from September 1994 to August 2026, totalling 178,556 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 $42K, with roughly $8K 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 44 barrels a month, about 22 per wellbore. Its strongest month on the record we hold was December 2016, at 532 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
