ZALMAN
ZALMAN is a Texas gas lease in Wharton County, Railroad Commission district 03, operated by Texstar North America, Inc. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 953,295 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 $609K, with roughly $189K 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 528 thousand cubic feet a month. Its strongest month on the record we hold was August 2021, at 2,948 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
