Laboratory measurements for the frequency dependence of Young's modulus E (a) and Poisson's ratio |$\nu $| (c), as well as the corresponding attenuation |$1/{Q_{\rm{E}}}$| (b) and |$1/{Q_{\rm{\nu }}}$| (d), and the derived bulk modulus K (e) and shear |$\mu $| modulus (f) for the tight sandstone saturated with nitrogen gas as functions of effective pressure |${P_{{\rm{eff}}}}$| with a maintained pore pressure at |${P_{\rm{P}}} = 1.2$| MPa, under temperature |$T = {23^{\rm{o}}}\,{\rm{C}}$|⁠. The core sample was investigated at room temperature under isotropic loading with atmospheric pore pressure. Each open circle symbol represents the mean measurement of three experiments, with their corresponding error bars illustrated. Dry elastic moduli show errors of around |$\pm 0.45$| GPa for (a), |$\pm 0.0035$| for (c), |$\pm 0.5$| GPa for (e) and |$\pm 0.4$| GPa for (f). (b) and (d) have an error of |$\pm 0.004$| and |$\pm 0.003$|⁠, respectively.
