Mineral compositional controls on the porosity of black shales from the Wufeng and Longmaxi Formations (Southern Sichuan Basin and its surroundings) and insights into shale diagenesis

Energy Exploration & Exploitation, 2018
The effects of brittle minerals in shale diagenesis on shale pores remain controversial and it is difficult to quantify directly. However, the relationship between brittle minerals and shale pores could provide indirect guidance regarding diagenesis ...

An experimental investigation of the thermophysical properties of shale reservoirs: a case study of the Wufeng-Longmaxi formation in the Jiaoshiba Area

Journal of Geophysics and Engineering
Abstract The production of shale oil and gas is increasingly recognized as being influenced by temperature fields. Hydraulic fracturing involves the injection of substantial amounts of fracturing fluid into the reservoir, which alters the temperature field distribution and, in turn, affects shale gas production.
