A new approach to estimating coal gas content for deep core sample

Fuel, 2020
Method to accurately estimate gas content in the deep-burial coals is still unavailable. To this end, a new method which avoids the underestimation of lost gas content during the retrieval process of deep-burial coal sample within boreholes was well ...

Effect of gas content in macropores on hydraulic fracturing in rocks using a fully coupled DEM/CFD approach

International journal for numerical and analytical methods in geomechanics (Print), 2020
The paper focuses on the effect of the gas content in rock macropores on a hydraulic fracturing process. The process was simulated by combining the discrete element method (DEM) with computational fluid dynamics (CFD) under two‐dimensional (2D ...

Experimental study on gas content of adsorption and desorption in Fuling shale gas field

Journal of Petroleum Science and Engineering, 2019
Shale gas mainly exists in organic-rich shale in the form of free gas and adsorbed gas. Shale gas content has a direct impact on the productivity and life of the gas well, and is also an important indicator for areal selection and reservoir evaluation ...

Geological controls on gas content distribution of coal seams in the Kınık coalfield, Soma Basin, Turkey

, 2020
The Miocene Soma Coal Basin may be one of the most promising areas for low-rank coalbed methane in Turkey. So far, the coalbed methane potential of the coal seams in the Kinik Coalfield, Soma Basin has not been adequately studied.
