DUSEK 45-4
DUSEK 45-4 is a Texas oil lease in Midland County, Railroad Commission district 7C, operated by Parsley Energy Operations, LLC. It has 2 wellbores on file with the Commission. Reported production runs from March 2014 to August 2026, totalling 898,336 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 $4.6M, with roughly $1.4M 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 1,922 barrels a month, about 961 per wellbore. Its strongest month on the record we hold was May 2016, at 11,792 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.
