Abstract Moisture in shales under reservoir conditions adversely affects gas adsorption and nanoporosity is also likely to impact on the contribution that kerogen makes methane capacity. To investigate these phenomena, two over mature from Wufeng-Longmaxi Formation, south of Sichuan basin, their kerogens isolated by demineralisation were investigated dry at 95% relative humidity (R.H.) high-pre...

Nitrogen adsorption experiments have been extensively applied to shale pore structure research and evaluation. The can be quantitatively characterized in accordance with the nitrogen adsorption–desorption isotherm using various calculation models, whereas results obtained different models more effectively indicate characteristics of remains unclear. Further, there has not any unified process op...

The shale gas resources in China have great potential and they are distributed 13 stratigraphic series from the Mesoproterozoic to Cenozoic. Organic-rich shales can be divided into three types according their sedimentary environments, namely marine, marine-continental transitional, continental shales. geological of is over 100 trillion m3, which includes 20 m3 recoverable resources. Sichuan Bas...
