SUNDANCE 642
SUNDANCE 642 is a Texas oil lease in Yoakum County, Railroad Commission district 8A, operated by Riley Exploration Opg Co, LLC. It has 5 wellbores on file with the Commission. Reported production runs from February 2017 to August 2026, totalling 243,388 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 $4.5M, with roughly $1.0M 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 4,858 barrels a month, about 972 per wellbore. Its strongest month on the record we hold was April 2026, at 14,680 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.
