Abstract
The hydro-thermo-mechanical and chemical properties of reservoir rocks and the surrounding sealing units are important data for assessing the performance of a CO2 storage. Laboratory measurements on rock samples are the first method to assess these properties and evaluate the reservoir injectivity and storage potential. Beyond standard techniques, this chapter also presents state of the art laboratory experiments capable of reproducing the in situ conditions during CO2 injection. In addition, these methods are also used to investigate the coupling between the hydro-thermo-mechanical and chemical properties.
