Stress history and reservoir pressure for improved quantification of CO2 storage contain-ment risks (SHARP Storage)

The main goal of the SHARP Storage project is to provide CO2 storage site operators with improved techniques for assessing and monitoring the risk of induced seismicity and gas leakage. This will be achieved through the improvement and integration of observations and models of subsurface stress, rock mechanical failure and seismicity.

The project consortium involves 16 academia and industry partners in Norway, UK, Denmark, the Netherlands, and India. The research and development will be carried out in five closely interlinked work packages (WPs): The development of the subsurface monitoring (WP4) and risk assessment (WP5) tools will be based on basin-scale geomechanical models of stress history (WP1), improved knowledge on the present-day stress field in the North Sea (WP2) and constitutive models of reservoir and cap rock from rock deformation (WP3).

The research activities will be focused on site development projects in the partner countries, including two potential CO2 storage sites in Denmark: 1) the Hanstholm saline aquifer and 2) the depleted Nini West field. The industrial uptake of the work will be ensured through the integrated industry involvement in the consortium.
