CATHY
CATHY is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Windsor Energy Group, L.L.C. It has 2 wellbores on file with the Commission. Reported production runs from September 2008 to August 2026, totalling 79,618 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 $1.0M, with roughly $220K 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 296 barrels a month, about 148 per wellbore. Its strongest month on the record we hold was January 2020, at 559 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.
