KOLLER
KOLLER is a Texas oil lease in Pecos County, Railroad Commission district 08, operated by Haylan Oil Company. It has 4 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 19,106 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 $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 4 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was January 2017, at 100 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
