INTRODUCTION
Welcome, Rune Aarlien

CO2 STORAGE
Introduction – BIGCCS paving the way for large-scale CO2 storage Grethe Tangen, Senior Researcher, SINTEF Petroleum Research
The ambition of the storage sub-program is to underpin deployment of CCS by maximizing CO2 storage capacity, minimizing uncertainty of CO2 storage and improving the business case by enabling CO2 EOR. Over the eight years, the eminent team of researchers together with industry partners have made great contributions. This was stated by SP leader Grethe Tangen when introducing the session on CO2 storage. Research institutions involved are BGS, GEUS, Lawrence Livermore National Laboratory together with NTNU and SINTEF.
Pressured by saturation and uncertainty? Monitoring helps! Peder Eliasson, Research Manager, SINTEF Petroleum Research
Task Leader Peder Eliasson, responsible for the monitoring activities in BIGCCS, presented significant achievements important for improving CO2 storage safety by accurately localizing the CO2 plume, quantifying CO2 volumes and enabling early detection of potential leakage. The research is conducted mainly by BGS, NTNU and SINTEF using data and experience from the industry projects Sleipner and Snøhvit.
Geomechanics, the libero player: From capacity estimate to monitoring via near-well integrity Pierre Cerasi, Research Manager, SINTEF Petroleum Research
Pierre Cerasi, task leader of CO2 containment, pointed out geomechanics as the safe-keeper of CO2 containment. He summarised new knowledge and experimental methods developed to prevent three possible integrity breach mechanisms: along injection wells, failure of sealing caprock and fault reactivation. Stress concentration and increase can lead to rock failure and thus should be confidently determined to set limits on pressure increase.
Geomechanical issues associated with CO2 storage reservoirs Sohrab Gheibi, PhD student, NTNU
PhD student Sohrab Gheibi followed up by explaining the effect of fault deformation on the stress changes and showing that, based on his PhD work, it is possible to predict the fracture initiation as well as fracture propagation. New code enables modelling of the time-dependent behavior of fractures or faults to ensure long-term stability, highly relevant for storage safety and capacity for CO2 EOR.
Avoiding CO2 leakage through active and abandoned wells Malin Torsæter, Senior Researcher, SINTEF Petroleum Research
Malin Torsæter, the leader of well integrity, pointed out that wells are structures of cement and steel and not just holes in the ground. New knowledge is generated and innovative methods on well cementing and cement bonding are developed to avoid that the wells become the weakest link of the CCS chain. Also, the task has advanced knowledge on how to make wells more robust to thermal variations and CO2 exposure.
Large-scale CO2 storage – The art of safely fitting cubic kilometres of CO2 into tiny rock pores Alv-Arne Grimstad, Senior Researcher, SINTEF Petroleum Research
Task leader Alv-Arne Grimstad, illustrated what large-scale storage of CO2 means: If 200 Mt CO2 is captured in Europe and stored in the North Sea at atmospheric conditions, it would represent blanket 2.5 m thick covering Denmark. Luckily CO2 can be compressed and the volume reduced by factor of more than 300. However, to maintain safety both structural and stratigraphic trapping are essential. The task has brought new knowledge on how much CO2 can be safely injected without compromising caprock integrity and has addressed how storage capacity can be managed safely through water production. Also, BIGCCS has advanced understanding of convective mixing as trapping mechanism and shown that residual trapping can contribute significantly even on short time scales.
CO2 TRANSPORT
CO2 Transport – achievements summary Task 2.1 and 2.2 Svend Tollak Munkejord, Chief Scientist, SINTEF Energy Research
Svend Tollak Munkejord at SINTEF Energy Research has led the sub programme on CO2 transport since the start in 2009. He emphasized that in order to reduce risk in CCS projects, quantitative knowledge is needed. He presented a coupled fluid-structure model predicting running-ductile fracture in CO2-transport pipelines, and accurate thermophysical data for CO2-rich mixtures.
BIGCCS, Gassco and CO2 transport Svein Solvang, Principal Engineer, Gassco
Svein Solvang described how the knowledge generated in BIGCCS has been used in technical CO2-transport studies conducted by Gassco. He also stated that with this knowledge, system design can be made less conservative.
