Abstract

Summary

This study aims to assess the mechanical properties of the mineral and organic phases of source rocks in order to provide consistent input data for effective medium modeling. To this end, nanoindentation measurements are combined with SEM-EDS analysis to match the measured mechanical properties to unequivocally identified mineral and organic phases. The defined workflow consists of four key steps: 1) preparation and characterization of the surface to be analyzed; 2) mechanical characterization through nanoindentation measurements; 3) localization of residual nanoindentation imprints and chemical characterization of indented phases through SEM-EDS analysis; 4) withdrawal of multiphase indentations and one-to-one association of mechanical properties to identified phases. The results obtained on a sample from the Montney formation (Western Canadian sedimentary basin) are presented to illustrate the key contribution of the positive identification of the indented phases through SEM-EDS analysis. The measured indentation moduli are consistent with nanoindentation data and elastic properties from the literature.
