HERRERA
HERRERA is a Texas gas lease in Duval County, Railroad Commission district 04, operated by Maynard Oil Co. It has 1 wellbore on file with the Commission. Reported production runs from March 2000 to August 2026, totalling 2,984,926 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 $62K, with roughly $9K 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 391 thousand cubic feet a month. Its strongest month on the record we hold was May 2018, at 2,275 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.
