HEFFELFINGER "A"

HEFFELFINGER "A" is a Texas gas lease in Matagorda County, Railroad Commission district 03, operated by Texegy Operating Company LLC. It has 1 wellbore on file with the Commission. Reported production runs from June 2017 to August 2026, totalling 1,192,486 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 a standard royalty share at about $6K, with roughly $1K expected over the next twelve months. Over the last twelve months on file it averaged 2,197 thousand cubic feet a month. Its strongest month on the record we hold was June 2017, at 101,388 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.

Production figures are as reported to the Railroad Commission of Texas. The value shown is an estimate produced by fitting a decline curve to that reported history; it is not an offer or an appraisal.
