KOSSTOHRYZ UNIT

KOSSTOHRYZ UNIT is a Texas oil lease in Burleson County, Railroad Commission district 03, operated by Williams, Clayton Energy, Inc. It has 1 wellbore on file with the Commission. Reported production runs from February 1997 to August 2026, totalling 251,252 barrels. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values a standard royalty share at about $42K, with roughly $12K expected over the next twelve months. Over the last twelve months on file it averaged 775 barrels a month. Its strongest month on the record we hold was July 2021, at 3,159 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.

Production figures are as reported to the Railroad Commission of Texas. The value shown is an estimate produced by fitting a decline curve to that reported history; it is not an offer or an appraisal.
