ELLIE

ELLIE is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Cog Operating LLC. It has 6 wellbores on file with the Commission. Reported production runs from January 2009 to August 2026, totalling 419,986 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 $1.4M, with roughly $467K 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 902 barrels a month, about 150 per wellbore. Its strongest month on the record we hold was May 2024, at 2,961 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.
