RANCHO GRANDE TRUST UNIT NO. 1

RANCHO GRANDE TRUST UNIT NO. 1 is a Texas gas lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from February 2017 to August 2026, totalling 935,464 thousand cubic feet. 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 $1.6M, with roughly $654K 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 2,648 thousand cubic feet a month. Its strongest month on the record we hold was March 2017, at 61,011 thousand cubic feet. 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.
