On Monday NOC scientists on board the STEMM-CCS expedition arrived in the southern Viking Graben (North Sea), where they carried out detailed mapping of a seismic chimney structure on the sea-floor. The purpose of the expedition is to investigate what role this chimney structure has for fluid migration. For geological carbon storage, subsurface chimney structures could have implications for the integrity of a storage reservoir, and therefore need careful investigation.
