This report summarizes the activities at the Laboratory of Soil Mechanics - Chair “Gaz Naturel” Petrosvibri at the Swiss Federal Institute of Technology in Lausanne (LMS-EPFL) related to the project “CAPROCK: Experimental assessment of geomechanics of deep carbon dioxide sequestration”. The support for the project was provided by the Swiss Federal Office of Energy and partially covered the activities of a postdoctoral researcher. The main goal of the project was building the expertise in experimental testing of geomechanical response of materials that possess properties of host and caprocks for geological storage of CO2. The characterization of changes in thermo-hydro-mechanical behaviour of rock due to high pressure CO2 injection through triaxial and oedometric compression tests, with microimaging techniques and the chemical analyses, was performed on the equipment developed at the LMS-EPFL or available at other laboratories at the EPFL. The report is organized in the following way. Personnel that participated to the project is listed in Chapter 2. Chapter 3 gives a brief summary of the postdoc’s research activities related to both laboratory experiments and modelling. Other activities, including published papers, conference presentations, and collaborations with other groups are provided in Chapter 4. Intermediate reports, conference abstracts and posters, and conference and journal papers are contained in the Appendices.
