CARTER UNIT
CARTER UNIT is a Texas oil lease in Caldwell County, Railroad Commission district 01, operated by North South Oil, LLC. It has 9 wellbores on file with the Commission. Reported production runs from April 2009 to August 2026, totalling 535,664 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 $1.5M, with roughly $481K 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 761 barrels a month, about 85 per wellbore. Its strongest month on the record we hold was August 2018, at 3,770 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.
