BROOK B-17B
BROOK B-17B is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Pioneer Natural Res. USA, Inc. It has 2 wellbores on file with the Commission. Reported production runs from June 2016 to August 2026, totalling 970,196 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 $13.2M, with roughly $3.2M 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 4,571 barrels a month, about 2,285 per wellbore. Its strongest month on the record we hold was October 2016, at 33,354 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.
