Data and Model Outputs for Spectral Accessibility and Fast-P Attenuation Sensitivity of Intrinsic scCO₂ Relaxation in Partially Saturated Sandstone

This dataset supports the study “Separation Between Spectral Accessibility and Fast-P Attenuation Sensitivity of Intrinsic scCO₂ Relaxation in Partially Saturated Sandstone.” It contains the model inputs, processed parameter sets, machine-readable numerical outputs, sensitivity-analysis results, and figure-source data used to evaluate the coupling between intrinsic scCO₂ relaxation, hydraulic pressure diffusion, and fast-P attenuation in partially saturated sandstone. The archived files include the Donnybrook reference-state parameters, exact pressure-diffusion accessibility results, attenuation-sensitive hydraulic scales, finite-distance waveform metrics, dynamic-drag sensitivity, passive frame-relaxation sensitivity, near-critical constitutive-strength sensitivity, Berea hydraulic-transfer results, threshold-sensitivity results, and machine-readable tables corresponding to the Supporting Information. Third-party publisher PDFs and externally archived proprietary or copyrighted source data are not redistributed. Their identities, references, and roles in the analysis are documented through the provenance information included with the dataset.
