2 REPP-CO2 Preparation of a REsearch Pilot Project on CO2 Geological Storage in the Czech Republic Příprava výzkumného pilotního projektu geologického ukládání CO2 v České republice

3 REPP-CO2 Coordinator: Czech Geological Survey (CGS) Partners: IRIS International Research Institute of Stavanger (IRIS) VŠB Technical University of Ostrava (VSB) ÚJV Řež, a.s. (UJV) Research Centre Řež (CVR) Miligal, s.r.o. (Miligal) Institute of Physics of the Earth, Masaryk University (UFZ)

4 REPP-CO2 Funding: Norway Grants Grant provider: Ministry of Finance Project partner: Ministry of Environment Project duration: 23/1/ /11/2016

5 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;

6 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;

7 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.

8 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 (Brno, Jeseník, Klárov, Barrandov)

20 Risk identification - Summary Main approach: Bow-tie analysis to map causes, preventive and mitigating barriers, and undesirable effects (to humans, operations and environment

21 LBr-1 status of wells Top of Lab Horizon Abandoned well Fault Pinch-out boundary Re-abandoned well Targeted well Gas zone Oil zone CZ SK

22 BR72 well design after original abandonment and re-abandonment

23 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
