“…Note that all fractions are given in vol%, which is more relevant for mechanical properties than wt% (for conversion see Rybacki et al, 2015). The composition of shales is estimated from data provided by Wang and Carr (2012), Sone and Zoback (2013), Gasparik et al (2014b), Rybacki et al (2015), Lora et al (2016), Herrmann et al (2018), and Kamali-Asl et al (2018.…”

“…Carbonate and quartz are the stiffest minerals in shale rocks, while clay minerals and organic matter are softer. Therefore, it would be reasonable to assume that an increase in "clay+TOC" content would result in lower bulk modulus values (i.e., higher pressure dependency of mechanical deformation) [31]. This might not be the case when minor mineralogical differences exist, although, it certainly holds as the difference becomes more significant.…”

“…The stress lag is normally noticed in the viscoelasticity medium. With a large content of clay, clay shale can be treated as the viscoelasticity medium (Arash et al 2018). Due to the property of viscoelasticity, stress inside rock normally lags behind stress outside rock, creating lag stress between stress inside and outside of core sample, as shown in Fig.…”
