Parallel computation for reservoir thermal simulation of multicomponent and multiphase fluid flow
We consider parallel computing technology for the thermal simulation of multicomponent, multiphase fluid flow in petroleum reservoirs. This paper reports the development and applications of a parallel thermal recovery simulation code. This code utilizes the message passing interface (MPI) library, overlapping domain decomposition, and dynamic memory allocation techniques. Its efficiency is investigated through simulation of two three-dimensional multicomponent, multiphase field models for heavy oil crudes. Numerical results for these two simulation models indicate that this parallel code can significantly improve capacity and efficiency for large-scale thermal simulations.
