LANGE E EFS
LANGE E EFS is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Sea Eagle Ford, LLC. It has 1 wellbore on file with the Commission. Reported production runs from July 2013 to August 2026, totalling 56,789 barrels. The lease is intermittent. 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 $11K, with roughly $2K 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 32 barrels a month. Its strongest month on the record we hold was May 2017, at 465 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
