WHL
WHL is a Texas oil lease in Ector County, Railroad Commission district 08, operated by Windsor Permian LLC. It has 20 wellbores on file with the Commission. Reported production runs from August 2010 to August 2026, totalling 786,327 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 $1.1M, with roughly $350K 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 644 barrels a month, about 32 per wellbore. Its strongest month on the record we hold was June 2016, at 4,124 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.
