LONG 13A
LONG 13A is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Athlon Fe Operating LLC. It has 3 wellbores on file with the Commission. Reported production runs from November 2012 to August 2026, totalling 90,696 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 $676K, with roughly $118K 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 139 barrels a month, about 46 per wellbore. Its strongest month on the record we hold was July 2016, at 715 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.
