OLD TOM UNIT B 21-28
OLD TOM UNIT B 21-28 is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Surge Operating, LLC. It has 5 wellbores on file with the Commission. Reported production runs from October 2017 to August 2026, totalling 1,857,332 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 $10.1M, with roughly $2.7M 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 3,376 barrels a month, about 675 per wellbore. Its strongest month on the record we hold was August 2018, at 124,166 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.
