In Situ Gas Content Prediction Method for Shale. [PDF]
ACS OmegaShale gas is a typical unconventional energy source and recently has received great attention around the world. Unlike conventional natural gas, shale gas mainly exists in two forms: free state and adsorbed state. Therefore, geologists have proposed the concept of gas content.

Discussion on determination of gas content of coal and uncertainties of measurement
International Journal of Mining Science and Technology, 2017 Gas content of coal is mostly determined using a direct method, particularly in coal mining where mine safety is of paramount importance. Direct method consists of measuring directly the volume of gas desorbed from coal in several steps, from solid then ...
