CALAMITY JANE
CALAMITY JANE is a Texas oil lease in Reeves County, Railroad Commission district 08, operated by Rosetta Resources Operating LP. It has 19 wellbores on file with the Commission. Reported production runs from July 2014 to August 2026, totalling 6,098,041 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 $41.1M, with roughly $13.9M 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 18,054 barrels a month, about 950 per wellbore. Its strongest month on the record we hold was January 2018, at 322,010 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
