Popis: Decarbonisation of the energy system requires new uses of porous subsurface reservoirs, where hot porous reservoirs can be utilised as sustainable sources of heat and electricity, while depleted ones can be employed to temporary store energy or permanently store waste. However, fluid injection induces a poro-elastic response of the reservoir rock, as well as a chemical response that is not well understood. We conducted uniaxial stress-cycling experiments on quartz sand aggregates to investigate the effect of pore fluid chemistry on short-term compaction. Two of the tested environments, low-vacuum (dry) and n-decane, were devoid of water, and the other environments included distilled water and five aqueous solutions with dissolved HCl and NaOH in various concentrations, covering pH values in the range 1 to 14. In addition, we collected acoustic emission data and performed microstructural analyses to gain insight into the deformation mechanisms. The data is provided in one folder for 26 experiments/samples. Detailed information about the files in these subfolders as well as information on how the data is processed is given in the explanatory file Schimmel-et-al_2020_data-description.docx.
