Description

The example-H4 concerns simulation of CO₂ injection in the Johansen formation using a real-scale geological model of the formation. We use the “sector model with heterogeneous rock properties”, which can be downloaded at www.sintef.no/Projectweb/MatMorA/Downloads/Johansen/. The model comprises 11 layers of grid blocks. There are 5 vertical faults in the model. We simulate two scenarios of CO₂ injection in this formation for two different locations of the injection well (INJ1 and INJ2) in the region of depression. The duration of the injection period is 100 years while the post-injection period, considered in here, is 2500 years. The injection results in two-phase buoyancy-driven flows of the formation water and supercritical CO₂. The CO₂ plume spreading along the caprock is strongly affected by the complicated geological settings, particularly by the local topology of the caprock.
