Shale gas content evolution in the Ordos Basin
International Journal of Coal Geology, 2019Gas content is a crucial parameter for shale reservoir evaluation and shale gas accumulation. Taking Shanxi and Taiyuan Formation shale samples from the Ordos Basin of China as an example, this research used thermal simulation, Rock-Eval pyrolysis, total

Coal Bed Gas Content and Gas Undersaturation
1999Undersaturation of coal with respect to gas is a major economic risk in the coal bed gas exploration. This communication addresses the following questions: (1) How much thermogenic gas is formed from coals at different levels of maturity? (2)What is the minimum rank at which a given coal has generated sufficient thermogenic gas to be saturated at ...

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 ...

The Measurement of Shale Gas Content
Applied Mechanics and Materials, 2013The gas content is critical parameter in the shale gas exploration and production. The direct method was used to determine the shale gas content and the apparatus were made by ourselves. It were described the gas content test procedure, mathematic model and data processing in the paper.
