UL MOCKINGBIRD 13-2 B
UL MOCKINGBIRD 13-2 B is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 1 wellbore on file with the Commission. Reported production runs from April 2022 to August 2026, totalling 321,502 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 $6.7M, with roughly $2.1M 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 3,239 barrels a month. Its strongest month on the record we hold was June 2022, at 24,957 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.
