HAMMAN 30D
HAMMAN 30D is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Earthstone Operating, LLC. It has 2 wellbores on file with the Commission. Reported production runs from February 2020 to August 2026, totalling 221,776 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 $1.9M, with roughly $802K 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 1,023 barrels a month, about 512 per wellbore. Its strongest month on the record we hold was April 2021, at 22,272 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.
