GWENDOLYN
GWENDOLYN is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Henry Resources LLC. It has 41 wellbores on file with the Commission. Reported production runs from February 2014 to August 2026, totalling 8,635,831 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 $80.3M, with roughly $23.7M 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 37,064 barrels a month, about 904 per wellbore. Its strongest month on the record we hold was April 2019, at 244,171 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.
