HARTMAN UNIT
HARTMAN UNIT is a Texas oil lease in Cooke County, Railroad Commission district 09, operated by West Bay Exploration Company. It has 2 wellbores on file with the Commission. Reported production runs from June 2001 to August 2026, totalling 32,505 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 $229K, with roughly $44K 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 61 barrels a month, about 30 per wellbore. Its strongest month on the record we hold was September 2019, at 125 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
