ISABELLE
ISABELLE is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Tidal Petroleum, Inc. It has 2 wellbores on file with the Commission. Reported production runs from June 2019 to August 2026, totalling 200,358 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 $2.0M, with roughly $448K 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 612 barrels a month, about 306 per wellbore. Its strongest month on the record we hold was July 2019, at 23,297 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.
