Structural evolution and characterization of organic-rich shale from macroscopic to microscopic resolution: The significance of tectonic activity [PDF]
, 2023 Shale gas exploration and development have taken significant strides in the relatively straightforward intra-basin stability zone and intra-basin weak deformation zone of marine shale in the Sichuan Basin, South China. In addition, the extra-basin strong

Geological difference and its significance of marine shale gases in South China
Petroleum Exploration and Development, 2016 Organic-rich marine shales are developed in both the Cambrian Qiongzhusi Formation and the Ordovician Wufeng Formation–Silurian Longmaxi Formation in South China, but are different in the drilling results of shale gas exploration.

Paleomagnetic results from the Silurian of the Yangtze paraplatform [PDF]
, 1987 Detailed sampling of two short magnetozones within the Matuyama Chronozone recorded at DSDP Site 609 (49.86°N, 335.77°E) confirms that one, the Cobb Mountain Subchronozone (1.12 Ma), is a very short, full normal polarity interval and that the other, the ...

Effects of pore connectivity and water saturation on matrix permeability of deep gas shale [PDF]
, 2022 Shale matrix permeability is an important indicator for evaluating gas transport and production. However, the effects of pore connectivity and water saturation on the matrix permeability in deep gas shales have not been adequately studied. In this study,

Reservoir energy response mechanism during shale gas accumulation in Longmaxi Formation
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In order to explore the microscopic energy response mechanism of the shale gas accumulation process in the Longmaxi Formation, the energy balance theory is taken as the core. Based on the tectonic evolution and hydrocarbon generation history simulation, the elastic energy and gas elasticity of the Longmaxi Formation shale ...
