The project completed with the last disputations the winter of 2013 and are summarized in the article The sealing is tight and the final report of the project that you find here.
Storage of CO2 in the subsurface is one strategy to reduce the CO2 emissions to the atmosphere. To achieve this in a safe manner and by that make the method acceptable to the public there is a need for knowledge of leakages from such storages over long time spans.
First of all there is a need to gain experience with the risks of leakage from oil wells and methods to detect them as well as better detect and find cracks in the subsurface which can give leakages and describe their potential. There is also a need to describe models which can combine hydrogeological, geochemical and geomechanical simulations. These models should be used as tools to predict the possibility for leakages through long time spans.
These types of problem will the project study in the five years project period, and by this contribute to reduced emissions of CO2 to the atmosphere.
Main objectives
To establish technology for risk assessment, monitoring, and remediation of CO2 stored in the subsurface for:
- Cap rock and overburden leakage including additional hydrate sealing.
- Well leakage.
Participants
The research project is in co-operation with four participants; University of Oslo - Department of Geosciences, University of Bergen - Department of Physics and Technology, Norwegian Geotechnical Institute and Institute for Energy Technology.
All the four participating institutions have solid experience in co-operation with the oil industry and have competence in CO2 storage through several projects.
Consortium
The project is founded by a consortium including the Norwegian government through The Research Council of Norway and oil companies with activities in CO2 storage as Conocophillips, Norske Shell, RWE Dea, Schlumberger and Statoil.
