Subsurface to Surface Network Modeling for CO2 Sequestration in a Deep Saline Aquifer

Integrating the subsurface model for CO2 sequestration with the surface facilities model is very important to ensure long term deliverability of CO2 to the subsurface formation. In this paper, A compositional dynamic reservoir model is fully implicitly integrated with wellbore and surface network model to evaluate CO2 sequestration in a deep saline aquifer, located offshore of the west coast of Norway. Major issues to consider are storage mechanisms, CO2 plume distribution, and processes that could potentially cause CO2 to leak out of the target formation and into the formations above. The integrated workflow allows the studies to incorporate uncertainties from static and dynamic properties through surface facility and well operating parameters.
