MARY ELLEN
MARY ELLEN is a Texas oil lease in Ector County, Railroad Commission district 08, operated by Exl Petroleum, LP. It has 18 wellbores on file with the Commission. Reported production runs from October 2007 to August 2026, totalling 1,467,628 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 $3.7M, with roughly $783K 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 837 barrels a month, about 46 per wellbore. Its strongest month on the record we hold was May 2016, at 6,834 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.
