The shale gas content of the Longmaxi Formation exhibits significant spatial variation in different structural parts of the Sangzhi area in Hubei Province, reflecting differences in preservation conditions. To quantitatively evaluate these conditions, this study integrates analyses of structural features, fault distribution, formation water chemistry, and shale gas composition from four wells. Results show that preservation is primarily controlled by the F1 and F3 faults. Wells distant from these faults (SY3 and SY5) display weak connectivity with surface water, feature CaCl2-type formation water with high salinity and diagnostic ion coefficients, and contain hydrocarbon gases derived from o...

Against the backdrop of a profound global energy transition and escalating ecological and environmental risks, the Journal of Geo-Energy and Environment (JGEE) is launched to build a high-level scholarly platform at the intersection of 'Geo-Energy–Environment–Ecology'. JGEE focuses on conventional fossil energy, geothermal energy, and natural gas hydrates, as well as new energy sources such as hydropower, photovoltaics, and hydrogen, and advocates a closed-loop and cross-scale integration of theory–technology–numerical simulation–experiment. It concentrates on energy–environment coupling and resource management, including Carbon capture, utilization, and storage (CCUS), methane m... More >
