BROOK D-15G
BROOK D-15G 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 December 2017 to August 2026, totalling 812,390 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 $3.6M, 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 1,588 barrels a month, about 794 per wellbore. Its strongest month on the record we hold was March 2018, at 33,788 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.
