Low‐frequency forced‐oscillation methods applied to a reservoir sandstone allowed determination of the Young's modulus and Poisson's ratio (from axial loading), bulk modulus (by oscillation of the confining pressure) and shear modulus (from torsi

Gassmann fluid substitution is widely used in geophysical practice. In the last few years, the topic of fluid/solid substitution has emerged, where the substances filling the pore space can be solids, fluids, or visco-elastic materials, such as heavy

Low-frequency measurements of the elastic properties rocks based on the forced-oscillation method is an emerging approach for calibration of well log and seismic measurements. The dispersive proper...

We describe the design and fabrication steps of a low-cost, modular experimental cell for flooding and X-ray tomography visualization of the rock samples at reservoir conditions (confining pressure up to 45 MPa, pore fluid pressure up to 20 MPa, and

Summary In this study, we demonstrate that the divergence of the boundary conditions from ideal can lead to a significant dispersion of the elastic moduli of a liquid-saturated rock measured in low-frequency experiments. In laboratory tests, the liqu

Summary In this study, we investigate the influence of the creep phenomenon on the drifts of the dynamic moduli of three sedimentary rocks represented by Savonnieres limestone, Berea sandstone and Eagle Ford shale. We report the results of the low-fr

Summary Quantifying the impact of pore fill on elastic properties of porous rocks is of ongoing interets in geophysics. Previous experiements show that the change of the solid pore fill can produce larger change in effective elastic properties of por

Summary We studied the influence of water saturation on the elastic and anisotropy parameters of the Wellington shale in the range of the seismic frequencies from 0.1 Hz to 100 Hz at a confining pressure of 6 MPa. The measurements were conducted on t
