BYRUM "4"
BYRUM "4" is a Texas gas lease in Roberts County, Railroad Commission district 10, operated by Cimarex Energy Co. Of Colorado. It has 1 wellbore on file with the Commission. Reported production runs from January 2007 to August 2026, totalling 827,738 thousand cubic feet. The lease is intermittent. 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 $2K, with roughly $270 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 5 thousand cubic feet a month. Its strongest month on the record we hold was November 2016, at 2,853 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
