CASSWIN E
CASSWIN E is a Texas oil lease in Loving County, Railroad Commission district 08, operated by Eog Resources, Inc. It has 1 wellbore on file with the Commission. Reported production runs from February 2023 to August 2026, totalling 513,279 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 $12.3M, with roughly $3.5M 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 5,324 barrels a month. Its strongest month on the record we hold was March 2023, at 76,913 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
