Abstract

Summary

Initial benchmarking of the OPM Flow simulator with the CO2STORE option and the Eclipse E300 compositional simulator on the Smeaheia regional model concludes that both simulators handle the needed complexity in the model and show good scalability up to 16 MPI processes on an Equinor workstation, but the OPM Flow simulator is significantly faster than E300 for this case. The OPM Flow simulator was also run on the Simula eX3 cluster and there it shows good scaling up-to 512 MPI processes, which means it can simulate the multi-million model in less than an hour. The E300 simulator uses the Peng-Robinson EOS model for CO2 and tabulated values for the brine properties assuming constant temperature while OPM Flow use Span-Wagner for CO2 and computes the properties directly and thus considers the initial temperature gradient in the model. The slight differences in the results between the simulators can be traced back to the different PVT models used by the simulators.
