This paper presents our work on simulation of large-scale black oil models on parallel computers. An in-house platform has been developed and a black oil simulator has been implemented based on this platform, which can handle the standard black oil model and oil-water model. Numerical methods and a new parallel preconditioner are introduced. The simulator uses MPI for communication among computation nodes and it is capable of simulating black oil models with hundreds of millions of grid cells. Numerical simulations show that our simulator has excellent scalability and it can speed simulations thousands of times faster.
