Knowledge about the elastic properties of clay is therefore essential for the interpretation and modeling of the seismic response of claybearing formations. However, due to the layered structure of clay, it is very difficult to investigate its elastic properties. We measured elastic properties of clay using atomic force acoustic microscopy (AFAM).The forces applied during the experiments were not higher than 50 nN. The adhesion forces were measured from the pull‐off forces and included into our calculations by means of the Derjaguin‐Mueller‐Toporov model for contact mechanics. The obtained values of the elastic modulus for clay varied from 10 to 17 GPa depending on various parameters that describe the dynamics of a vibrating beam.Permalink: https://doi.org/10.1190/1.2147981FiguresReferencesRelatedDetailsCited ByPrediction of sonic velocities in shale from porosity and clay fraction obtained from logs — A North Sea well case studyMarina Pervukhina, Pavel Golodoniuc, Boris Gurevich, Michael B.
