The Halten Terrace site, Mid Norway

Halten Terrace site, Norway
Characterisation of a multi-compartment storage complex, Mid Norway
Lithostratigraphic column from Mid-Norway that shows the Garn Formation in the Fangst Group (yellow colour) that is planned as the CO2 storage unit. The caprocks above are the shale layers (Viking Group, Cromer Knoll and Shetland Group). From Dalland et al. (1998).
The Halten Terrace area is situated offshore Mid-Norway, and the basin covers an area of 150x50 km. The area contains gas with natural high CO2 content that can be extracted and stored. Both saline formation and dry structures may be possible storage sites, where both the potential reservoir and seals are of Mesozoic age. The Halten Terrace area has possible offshore sites, with reservoir boundaries defined by fault compartments. These will influence possible migration of the planned stored CO2 and possible fluid flow.
The main aim of the work being done is to use several simulation tools and software to evaluate where it would be safe to store CO2 in the underground and avoid leakage to the surface. This will be carried out on basin scale and on reservoir scale. The study will implement and compare different approaches to assess the impact of stress and pressure changes on CO2 storage performance and related risk at basin and storage compartment scale.
Considering data (formation properties and faults), model and scenario uncertainties, determine effective injection, monitoring and remediation strategies with emphasis on storage capacity optimisation.
