Reservoir modelling - coupled processes

The objectives of this work shall contribute to a better understanding of processes that occur during CO₂ storage. Coupled processes (mass- and heat transfer, compression and temperature effects) are supposed to be simulated. The focus here lies on subsurface processes that occur during injection and in the reservoir.

Phase changes in the injection well between liquid and gaseous should be avoided. This can be ensured by heating of the CO₂. Based on pressure data and fibre-optical temperature data a methodology is going to be developed  that describes the thermodynamic processes in the injection well. The results are important for monitoring and to may be used to minimize heating of the CO₂ stream.

The management of a CO₂ storage reservoir depends on rock parameters and geometry of the reservoir. Based on inverse modeling there will be developed a method to quantify the reservoir parameters using operational data.

The interplay between all components is of high importance for the effective design of a CCS (Carbon Capture and Storage) process chain. Until now only scarce experience exists with regard to design and operation that are intended to be reduced by this work package. A model of the process chain shall identify critical points of the process in advance and contribute to a smooth operation.
