IRVIN C UNIT

IRVIN C UNIT is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Carrizo Oil & Gas, Inc. It has 1 wellbore on file with the Commission. Reported production runs from August 2012 to August 2026, totalling 298,523 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 $3.2M, with roughly $1.2M 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 2,902 barrels a month. Its strongest month on the record we hold was March 2025, at 5,551 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.
