TRIAL UNIT
TRIAL UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 5 wellbores on file with the Commission. Reported production runs from September 2016 to August 2026, totalling 1,281,116 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 $2.6M, with roughly $684K 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 1,183 barrels a month, about 237 per wellbore. Its strongest month on the record we hold was October 2016, at 109,213 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.
