JAPSON 1B
JAPSON 1B is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Conocophillips Company. It has 1 wellbore on file with the Commission. Reported production runs from June 2025 to August 2026, totalling 68,792 barrels. The lease is intermittent. 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 $20.6M, with roughly $11.1M 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 5,077 barrels a month. Its strongest month on the record we hold was March 2026, at 21,812 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.
