GUAJILLO UNIT 10 NORTH
GUAJILLO UNIT 10 NORTH is a Texas oil lease in Live Oak County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 4 wellbores on file with the Commission. Reported production runs from November 2016 to August 2026, totalling 737,320 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 $1.8M, with roughly $603K 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 966 barrels a month, about 241 per wellbore. Its strongest month on the record we hold was November 2016, at 92,661 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.
