WINDHAM 11X
WINDHAM 11X is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Encana Oil & Gas(USA) Inc. It has 4 wellbores on file with the Commission. Reported production runs from August 2016 to August 2026, totalling 1,130,999 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 $6.0M, with roughly $1.7M 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 2,668 barrels a month, about 667 per wellbore. Its strongest month on the record we hold was December 2016, at 46,087 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
