Plug-core petrophysical, mechanical, acoustic, and mineralogical data for mineralogically contrasting shales

This dataset contains plug-core petrophysical, mechanical, acoustic, and formation-scale mineralogical data for four mineralogically contrasting shale formations: Onnagawa, Eagle Ford, Kushiro, and Montney. The dataset supports analyses of static–dynamic elastic-property relationships, velocity-based geomechanical correlations, and formation-dependent differences in dynamic-to-static modulus ratios. The repository includes a compiled Excel data file, MATLAB scripts used to generate figures and summary plots, and a README file describing the dataset structure, major variables, processing notes, and limitations.
