Abstract
Summary
Building on the successful Sleipner CO2 storage project in the Norwegian North Sea, the Utsira Formation has been proposed as large-scale CO2 storage reservoir. Given its shallow depth with regard to phase transition of the injected CO2, the integrity of the approx. 800m thick seal is of great importance. We show a case study of the Greater Sleipner Area where acquisition of sonar data revealed a fracture on the seafloor. This has led us to investigate the shallow subsurface in this area with regard to seal integrity using 3D seismic data. This paper presents results from seismic investigation of the seafloor fracture and its surrounding.
