Video Microscopy of Methane Gas Production From CBM Coals

摘要

This invention relates a method and apparatus for studying the desorption of gases from coals using optical microscopy. Such desorption reveals the ways in which production of gas from coal occurs under various completion and production scenarios. It can also reveal the efficacy of various stimulation and enhancement methods. The invention discloses methods and apparatus that enable simulation of coalbed reservoirs in a laboratory, and teaches how correlating various analytical techniques with said microscopy can allow researchers to readily evaluate coalbed reservoir properties and production factors.
