Clay is sediments or rocks with greater than 67% clay-size (2 micrometers or less) or colloidal size particles. If the rock is unindurated, it is clay; if the rock is indurated, it is a claystone; if the rock is indurated and laminated, it is shale. If appreciable amount (34% or greater) of silt is present in an indurated clay-rich rock, the ...Dec 1, 2012 · The differences between siliceous shale and silty shale in- clude (1) silicon sources: silicon is mainly authigenic, maybe biogenic, chemogenic or mechanical in siliceous shale, while is mainly exogenous quartz in silty shale; (2) silicon texture: silicon is mainly amorphous, cryptocrystal and micritic in siliceous shale, while exists as quartz ... upward-fining from siltstone and silty shale to shale, slightly deformed, Well Yuye 1 at a depth of 63.8 m.

Shale gas is one of the hot spots of energy development. Due to the strong heterogeneity and low physical properties of shale gas reservoirs, and the complex influencing factors of pore development, it is necessary to conduct a comprehensive analysis of the control factors of high-quality reservoirs.

However, the influence of shale-total organic content (TOC) on wettability (and thus on storage potential) has not been evaluated despite the fact that naturally occurring shale formations can vary dramatically in TOC, and that even minute TOC strongly affects storage capacities and ...

Jul 31, 2022 · Taking the shale line as the boundary, lithologies with Si content above the shale line is interpreted as silty laminated shale, while the lithologies with Ca abundance greater than 8.95% and plots below the shale line is interpreted as calcareous laminated shale, the rest of data represent argillaceous shales (3) A test from Well Y2 shows that ...
