MANGROVE J
MANGROVE J is a Texas oil lease in Gonzales County, Railroad Commission district 01, operated by Eog Resources, Inc. It has 1 wellbore on file with the Commission. Reported production runs from April 2020 to August 2026, totalling 319,848 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 $2.1M, with roughly $805K 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 1,273 barrels a month. Its strongest month on the record we hold was September 2020, at 37,706 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.
