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.
