WHITAKER 21-28 UNIT
WHITAKER 21-28 UNIT is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Qstar Operating LLC. It has 6 wellbores on file with the Commission. Reported production runs from March 2016 to August 2026, totalling 1,897,315 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 $27.9M, with roughly $7.5M 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 11,108 barrels a month, about 1,851 per wellbore. Its strongest month on the record we hold was August 2021, at 91,592 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.
