ULLMAN UNIT
ULLMAN UNIT is a Texas oil lease in Gonzales County, Railroad Commission district 01, operated by Eog Resources, Inc. It has 4 wellbores on file with the Commission. Reported production runs from December 2010 to August 2026, totalling 579,838 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 $2.2M, with roughly $647K 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 1,012 barrels a month, about 253 per wellbore. Its strongest month on the record we hold was July 2024, at 6,876 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.
