SHACKELFORD SPRABERRY UNIT
SHACKELFORD SPRABERRY UNIT is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Parker & Parsley Development Co. It has 637 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 36,403,830 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 $184.6M, with roughly $40.1M 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 85,145 barrels a month, about 134 per wellbore. Its strongest month on the record we hold was July 2022, at 230,995 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
