Distributed-memory parallel computer architectures appear to offer high performance at moderate cost for reservoir simulation applications. In particular, the simulation of compositional reservoir phenomena shows great promise for parallel applications because of the large parallel content of the compositional formulations. This paper focuses on the application of a distributed-memory parallel computer, the iPSC/860, to the solution of two compositional simulations: one based on the Third SPE Comparative Solution problem and another based on a real production compositional model. An improved linear equation solution technique based on multigrid and domain decomposition methods is compared with other techniques in serial and parallel environments. For a hypothetical heterogeneous example, the new technique showed a high degree of parallel efficiency. Finally, results show that performance of the compositional simulations with a fully parallel simulator is comparable to that of current mainframe supercomputers.
