Natural fractures, like tectoclases, are essential in the formation of shale gas reservoirs and
have been the focus of study for shale gas development. Tectoclases provide most storage …

The Weirong shale gas field, located within a low-steep structural belt in southern Sichuan
Basin, China, is characterized by gentle structural deformation. Production results have …

The deeply buried carbonates in the Sinian Dengying Formation are one of the crucial
hydrocarbon exploration targets in the central Sichuan Basin of China, and are …

Abstract In the Sichuan Basin, geologic conditions are complex in deep layers. Burial depth
of shale reservoirs is high. Gas well productivity is widespread low, and hydraulic fracturing …

The lamellation fractures in marine shales are important to the accumulation and
preservation of shale gas, whose characteristics and controlling factors are still unclear. This …

Tight-sandstone gas reservoirs have low porosity and contain developed microcracks, result
in the strong matrix heterogeneity. Due to the development of microcracks in tight sandstone …

Abstract The Bozi-Dabei area in the Kuqa Depression host high-quality reservoirs in the
Bashijiqike Formation and Baxigai Formation sandstones of the Lower Cretaceous, in which …
