| Zusammenfassung |
| We give an overview of the reservoir simulator MUFITS capabilities for modelling
underground carbon dioxide storage using the EOS-modules GASSTORE and BLACKOIL.
The GASSTORE module covers three-phase solid-liquid-gas flows of water, carbon dioxide
and salt components. The extended black-oil model is utilized in the BLACKOIL
module, which can be applied in the CO2 storage scenarios to two-phase flows of
CO2 and brine components. The modules allow comprehensive options including
salt precipitation/dissolution, thermal processes, multiple properties regions, and
complicated initial vertical equilibration. The PVT tables for the BLACKOIL module can
be generated automatically from the GASSTORE module for a given reservoir
temperature and brine salinity. We test the simulator against published benchmarking
studies.
We then consider an application case of CO2 storage at the Ketzin pilot site in Germany.
For that purpose, we use a calibrated 3D geological reservoir model comprising a highly
heterogeneous distribution of porosity and permeability in a fluvial geological setting. The
simulation is conducted using the EOS-module BLACKOIL and the modelling results are in
excellent agreement with the results of the industrial simulators applied in previous
benchmarks. In particular, the bottom-hole pressure in the injection well, the total mass of
dissolved CO2 and spatial CO2 distribution are identical with previously published
results. |
