Tendency to chemical cement. Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs. These rocks are classified on the proportions of vitric, crystal (mineral), or lithic material they contain, for example, "vitric lithic ash," or "crystal ...Shale oil obtained on thermal destruction of oil shale is a very specific product and its composition and properties depend both on the chemical composition of the concrete oil shale destructed and the conditions of destruction used. So, even using unified conditions of thermal processing it is practically not possible to produce similar shaleGas storage and recovery processes in shales critically depend on nano-scale porosity and chemical composition, but information about the nanoscale pore geometry and connectivity of kerogen ...2016.69082. 1.

Based on the above laboratory experimental results of shale composition, structural, physical, and chemical characteristics, it is noted that content of brittle mineral and clay mineral is very high in the component, showing moderate swelling and dispersion, and has a certain hydration effect.Test water samples. Because of its high productivity, the Longmaxi Formation is the most active shale gas production area in the Sichuan Basin. The shale formations in this area are complicated and characterized by high temperatures and pressures, high porosity (3.0–4.8%), and deep burial depths (1500–4500 m) (Zou et al. 2010).Water samples were collected in 50-L polyethylene barrels and 1 ...Kerogen, complex waxy mixture of hydrocarbon compounds that is the primary organic component of oil shale. Kerogen consists mainly of paraffin hydrocarbons, though the solid mixture also incorporates nitrogen and sulfur. Kerogen is insoluble in water and in organic solvents such as benzene or.According to different mineral compositions (clay minerals, carbonate minerals, and siliceous minerals), the three-end member method is used to make triangle diagrams, and four types of shale ...

The introduction of ILs chemicals for shale inhibition is considered a breakthrough and has found application in several industrial processes (Berry et al., 2008; Jia et al., 2020; Kuang et al., 2007; Yang and Pan, 2005). A state-of-the-art review on the application of ionic liquids as shale inhibitors is reported by (Rahman et al., 2020).These forces are function of the composition, type, amount, and micro-fabric of the clay content in the rock which are responsible for the global shale behavior, where water content and water distribution are the partial results of these forces. van Oort (2003) explains that when a shale is drilled, cuttings experience relief of in-situ stress.

The chemical composition of siliciclastic sediments has been extensively used to identify the features of the source rocks [8,9,10]. The relative variation of major components within shale determines the tectonic setting of sedimentary basins [ 11 ].The chemical composition and properties of fuel-shale briquets produced from tailings at the Leningradsk shale field are studied. The main problem in the processing and use of fuel shale in the ...
