SUMMERS, BRUNI
SUMMERS, BRUNI is a Texas gas lease in Webb County, Railroad Commission district 04, operated by Calpine Natural Gas L.P. It has 1 wellbore on file with the Commission. Reported production runs from August 2003 to August 2026, totalling 81,952 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 $13K, with roughly $2K 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 51 thousand cubic feet a month. Its strongest month on the record we hold was March 2021, at 224 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
