REPP-CO2
• Funding: Norway Grants • Grant provider: Ministry of Finance • Project partner: Ministry of Environment • Project duration: 23/1/2015 – 30/11/2016
Project objectives
(i) Assess the selected geological structure (a depleted oilfield) as a possible geological storage site for a research CO2 storage pilot project, utilising the methodology according to the Czech national law No 85/2012 Coll. on the storage of carbon dioxide in natural geological structures; (ii) Strengthen the Czech-Norwegian cooperation in the area of CO2 geological storage and related research and development;
Project objectives
(iii) Test the methodology, procedures and criteria for description and assessment of a planned CO2 storage complex as specified by the law No 85/2012 Coll. on the storage of carbon dioxide in natural geological structures under real conditions of a concrete storage site preparation; (iv) Perform geological modelling of the storage site and subsequent numerical simulation of CO2 injection;
Project objectives
(v) Perform a risk analysis of the storage site, including assessment of conflicts of interest, proposal of risk mitigation measures and compilation of storage site monitoring plan; (vi) Newly assess the potential of the Carpathian rock formations in the area of the Czech Republic from the CO2 storage point of view.
Project complexity
Team work, cooperation and keeping deadlines are essential: • 10 Activities • 54 Tasks • >109 researchers and technicians from
7 institutions • CGS - > 50 collaborators from 4 workplaces

Future steps • Finalisation of dynamic modelling and
simulations of CO2 injection into the reservoir • Finalisation of risk analysis – quantification of
risks, tool for evaluation of abandoned wells • Drafting of final monitoring plan • Scenarios for further development of the pilot
project • Lessons learned • Final project conference & workshop in Norway
