HEMBY UNIT B
HEMBY UNIT B is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 10 wellbores on file with the Commission. Reported production runs from August 2012 to August 2026, totalling 969,008 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 $2.9M, with roughly $815K 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 1,265 barrels a month, about 126 per wellbore. Its strongest month on the record we hold was June 2023, at 95,992 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.
