IRVIN EAST
IRVIN EAST is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Carrizo Oil & Gas, Inc. It has 36 wellbores on file with the Commission. Reported production runs from October 2011 to August 2026, totalling 8,112,677 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 $46.0M, with roughly $14.3M 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 22,727 barrels a month, about 631 per wellbore. Its strongest month on the record we hold was December 2018, at 166,168 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
