摘要：

In this study, sandstone samples from North-West Germany were investigated for potential geochemical, fluid chemical and petrophysical reactions induced during CO2 storage. To this purpose, autoclave experiments were conducted under reservoir temperature and pressure conditions. For each batch experiment, the sample was treated with synthetic brine in an autoclave, being either partly or completely submerged. CO2 was injected from the top. The dissolution of carbonate and sulfate cements were detected. Minor reactions in oolites were recognized and no alterations of the grains were documented. The basic petrophysical properties of the samples were increased by the reaction induced through the experiments. (C) 2017 The Authors. Published by Elsevier Ltd.
