UNDERWOOD
UNDERWOOD is a Texas gas lease in Harrison County, Railroad Commission district 06, operated by GMX Resources Inc. It has 1 wellbore on file with the Commission. Reported production runs from June 2006 to August 2026, totalling 414,970 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 $140K, with roughly $26K 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 1,073 thousand cubic feet a month. Its strongest month on the record we hold was March 2024, at 4,806 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.
