oa Svelvik CO2 Field Lab: Upgrade And Experimental Campaign

A small-scale CO2 field laboratory was established at Svelvik, Norway during 2009–2013. The original intent was to use the field lab for CO2 migration monitoring studies. Findings during the construction of the lab and during the initial experimental campaign indicated that the field lab is better suited for research on monitoring of CO2 storage. The suitability of the field lab for such research was further confirmed in 2013 by feasibility studies based on CO2 injection simulations and sensitivity studies for various geophysical methods. Since 2017, SINTEF is working, within the ECCSEL consortium, on upgrading the field lab with additional monitoring wells, instrumentation for cross-well seismic and ERT, and trenched DAS cables. The upgrade of the lab will be completed in spring 2019, and several new research projects have plans for experiments. The first new experimental campaign will be conducted during 2019 within the Pre-ACT project with the objective to produce field data and develop methods for quantification and discrimination of pressure and saturation changes in the subsurface, caused by CO2 injection.
