LANGE, WILLIAM A
LANGE, WILLIAM A is a Texas oil lease in Burleson County, Railroad Commission district 03, operated by Union Pacific Resources Company. It has 3 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 98,826 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 $879K, with roughly $149K 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 139 barrels a month, about 46 per wellbore. Its strongest month on the record we hold was June 2020, at 485 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.
