COX 21

COX 21 is a Texas oil lease in Glasscock County, Railroad Commission district 08, operated by Burleson Petroleum, Inc. It has 3 wellbores on file with the Commission. Reported production runs from July 2011 to August 2026, totalling 271,869 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 $51K, with roughly $11K expected over the next twelve months. Over the last twelve months on file it averaged 445 barrels a month, about 148 per wellbore. Its strongest month on the record we hold was May 2016, at 2,592 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.
