THORNBERRY 5A
THORNBERRY 5A is a Texas oil lease in Andrews County, Railroad Commission district 08, operated by Ok Arena Operating Company. It has 3 wellbores on file with the Commission. Reported production runs from October 2008 to August 2026, totalling 34,328 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 $118K, with roughly $22K 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 29 barrels a month, about 10 per wellbore. Its strongest month on the record we hold was July 2020, at 127 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.
