CROMWELL
CROMWELL is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Cheyenne Petroleum Company. It has 7 wellbores on file with the Commission. Reported production runs from June 2011 to August 2026, totalling 897,399 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 $1.5M, with roughly $501K 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 998 barrels a month, about 143 per wellbore. Its strongest month on the record we hold was June 2021, at 10,246 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.
