The shale samples, however, are classified as siliceous shale, calcareous shale and mixed shale as shown in the mineral composition ternary diagram (Fig. 2, Fig. 7 b). The clustered data distribution indicates the similarity in mineral composition and difference in TOC values for the first and third members of the Shahejie Formation.The marine black shale formations on the Upper Yangtze Platform, South China, are currently exploration targets for shale gas. Here, we report on the mineralogy, lithofacies, petrophysics, and ...Nov 1, 2022 · Based on the lithologic observations of shale microstructure, it is reported that shale is formed by the compaction of mechanically various particles like quartz, clay minerals, and organic matter. 12, 13 Mineralogical composition is an important factor that influences the mechanical property of shale. 14 The understanding of the mechanical ... Currently, Luzhou in the Sichuan Basin is a focal point for shale-gas exploration and development in China. However, a lack of detailed research on the mineral composition of the Wufeng Formation-Longmaxi Formation (WF-LF) shale is hindering the extraction of deep-buried shale gas in the Luzhou shale play. Herein, a field emission scanning electron microscope (FESEM) equipped with the Advanced ...
Schist ( / ˈʃɪst / SHIST) is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture reflects a high content of platy minerals, such as micas ...The alterations of the mechanical properties of shale matrix minerals can provide insights into the compressibility of fracture networks and the evolutionary laws of shale's micromechanical properties, and then revealing the inner weakening mechanisms of shale's macro-mechanical properties in the process of ScCO 2 fracturing and CO 2-enhanced ...Shale systems are severely heterogeneous. Figure1illustrates the mineral composi-tions of Barnett shale from Fort Worth Basin [30] and Chang 7 shale from Ordos Basin [6]. There is significant variation in mineral compositions of shales, even from the same for-mation. Shale oil movability is closely related to the minerals, pore structure, pore ... ….

With such model-based processing ...Jun 6, 2022 · The evaluation of rock mechanic characteristics of shale reservoir is the key for the success of fracturing. Several limitations such as complex lithology can affect the accuracy of the rock mechanic property computation. In this research, the mechanical rock properties of shale reservoirs were analyzed based on experimental tests including shale-reservoir mineral composition, uniaxial ...
Jul 12, 2022 · The microstructure of shale reservoirs refers to the distribution of mineral–organic matter, pore–fracture features, diagenetic processes, and their interrelations. The comprehensive and accurate analysis of the shale microstructure plays a critical role in formulating a reasonable development plan and optimizing measures to enhance oil or gas recovery. To explore the microstructure ... Uses: This shale is the raw material for the brick manufacturing industry in Ontario. Shale samples courtesy of Hanson Brick Ltd. Slate. Rock Type: metamorphic Composition: clay minerals Original Rock: shale Environment: Slate forms from the heat and pressure when shale is buried deep in the crust. The depth of burial to make slate out of shale ...Phyllite is a foliated metamorphic rock that has been subjected to low levels of heat, pressure and chemical activity. It is composed mainly of flake-shaped mica minerals in parallel alignment. The strong parallel alignment of the mica grains allows the rock to be easily split into sheets or slabs.
