Abstract

The study presents experimental results illustrating a certain tendencies in the change in physical and mechanical properties of the Vendian clay formations over depth. A comparative analysis of samples from different borehole intervals has arrived at significant coefficients of correlation for the parameters that characterize the degree of the clay water saturation, compaction, and consistency with depth (the elevation of the core-bore sample in the profile). The rock deformation and strength parameters also demonstrate a dependence on the depth. The deformation modulus and the shear strength of the clay increase with increase in the depth of sampling.
