Work Package # 2

Work Package 2: Modelling multi-phase reactive transport of CO₂ in aquifers: Team Leader Karsten H.Jensen (IGG, KU): participants Karsten Pruess (Lawrence Berkeley National Laboratory), Jacob Gudbjerg (consultant), Torben O. Sonnenborg (GEUS), post. doc. Flemming Damgaard Christensen (Rambøll).

This work package will focus on further development of a general simulation code TOUGH, which is developed by researchers at the Lawrence Berkeley National Laboratory. The aim will be to enable the code to handle the migration of CO₂ in the subsurface describing all possible phase combinations (supercritical, liquid and gaseous) and the geochemical reactions associated with geological storage of CO₂. The work will be carried out in collaboration with researchers from the Lawrence Berkeley National Laboratory. The code will be used to simulate the entire pathway if CO₂ leaks from an underground storage facility at supercritical state and moves to the surface including geochemical reactions. Such simulations are a prerequisite for doing a thorough risk assessment of geological storage of CO₂.
