CMG Ltd Online Course: CO2 Sequestration Using GEM – 19-20 May 2020

Run by the Computer Modelling Group Ltd, this course gives an overview of the modelling options built into the GEM simulator for CO2 Storage and Capture in an aquifer. A 2D model will be built and various CCS modelling tools will be progressively added on, starting from simple structural trapping down to mineralisation. The effect of each added process will be analysed in detail. The PVT package WinProp will be used for inputting the components properties and the aqueous and mineral reactions. The course will touch on the geochemical modelling features of GEM and its geomechanical modelling capabilities.
