FAT BOY
FAT BOY is a Texas oil lease in Ward County, Railroad Commission district 08, operated by Roca Resource Company, Inc. It has 1 wellbore on file with the Commission. Reported production runs from August 2000 to August 2026, totalling 159,023 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 $787K, with roughly $151K 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 237 barrels a month. Its strongest month on the record we hold was October 2017, at 1,040 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.
