The modelling suggests that the effect of clays in sandstone pores is to reduce the sample porosity without reducing the non-framework (void + clay) volume. Thus, for a given porosity, clay-rich samples contain greater non-framework volume, which in turn lowers velocity. The model derived ...

It consists of glauconitic and pyretic sandstone interbedded with shales, siltstones and carbonates [4]. Ref. [16] introduced the first name of Bahariya Formation, at its type locality is Gabel El Dist, Bahariya Oasis. Bahariya-1 well is the type locality for the subsurface Bahariya Format...
Since medieval times, Sander sandstone has been extensively used as a masonry material in Germany and other European countries for the building of houses, monuments and churches. In Germany, there are thousands of historical buildings which are made from natural stones, mostly sandstone, representing...
7 simulated the F–T weathering process of red sandstone, and analyzed the variation of rock strength, stress–strain curve and damage propagation mechanical properties with the number of F–T cycles. Kodama et al.8 explored the influence of strain rate, water content and temperature on the ...
Nowadays the problem of the efficient methods for exploring unconventional reservoirs and poor reservoir rocks are of great importance. Such rocks include the "ryabchik"-type AV1 horizon of Las-Egansky oilfield, represented by interbedded fine layers of sandstone, silt-stone and claystone. This ho...
