Critial assessment of coalbed reservoir gas-in-place analysis methods

摘要

Accurately detemining the gas-in-place volume is a crucial element of coalbed gas resource and reservoir evalaution. Different reservoir property analysis methods can yield very different gas resource and gas-in-place values. This paper presents results from evalautions of the accuracy of commonly used reservoir property analysis methods. Many commonly used analysis methods were found to have inherent shortcomings that can result in large (50
