Svelvik CO2 Field Lab - Update on Site Behaviour and Fluid Migration During CO2 Injection

The Svelvik CO2 Field Lab was designed for the development and testing of methods for quantifying saturation and pressure, in particular for CO2 monitoring applications. We present an update on the knowledge about the migration and distribution of the injected CO2 in the subsurface at the Svelvik CO2 Field Lab to facilitate planning for future experiments at the test site. Based on observations of site behaviour during water and CO2 injection and the corresponding effects on the seismic data, we develop an understanding of the migration of the CO2 from the injection point at 65 m depth, both in space and time. The purpose of this presentation is to provide potential users of the site an understanding of which scenarios can be observed at the Svelvik CO2 Field Lab (e.g., CO2 plume, migration of small amounts of CO2, leakage around wells, and potentially CO2 dissolution), and how to plan acquisition of the desired data.
