Smeaheia CO2 Storage Prospect Reference Dataset

The Smeaheia dataset is a reference dataset containing subsurface data, reports and geomodels related to assessment of proposed CO2 storage sites in the Smeaheia region, Hordaland Platform offshore Norway. Smeaheia has been under consideration as a possible site for storage of CO2 both as part of the Northern Lights full-scale CCS project in Norway, as well as for earlier projects (such as previous plans for a CO2 capture at Mongstad). The site is of continued interest for future storage.

Investigations into the site were carried out in several stages. Firstly, Gassnova carried out a pre-feasibility study from 2009 to 2012 into the Troll Kystnær area, which generally coincides with the location of the Smeaheia site. Work from this investigation was used as the starting point of a second feasibility study at the site, undertaken in 2016 by Equinor.

From the pre-feasibility phase this dataset contains 2D and 3D seismic data, well reports, pressure and temperature data, geomechanical and stress data, a static geomodel and a dynamic simulation model. The data from the feasibility study includes some re-interpretation of the existing seismic data and a new simulation model.
