DETERMINATION OF COAL BED NATURAL GAS PRODUCTION FACTORS AND A SYSTEM TO DETERMINE SAME

摘要

This invention relates to a method and system of determining gas content, critical desorption pressure, and/or other reservoir and operational variables, referred to as production factors, for coalbed natural gas wells. In particular, this invention relates to a method and system for measuring a partial pressure of methane or a predictor substance or a methane concentration for a coalbed natural gas reservoir and determining production factors therefrom.
