BIG BERTHA 0310 A
BIG BERTHA 0310 A is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Firebird Energy II LLC. It has 2 wellbores on file with the Commission. Reported production runs from September 2024 to August 2026, totalling 244,298 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 $11.2M, with roughly $4.6M 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 15,297 barrels a month, about 7,649 per wellbore. Its strongest month on the record we hold was April 2025, at 49,450 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
