This paper presents our work on developing parallel reservoir simulators for improving oil recovery on distributed-memory parallel systems and studying the scalability of our parallel reservoir simulators. The reservoir simulators are based on our in-house parallel platform, PRSI (Parallel Reservoir Simulation Infrastructure), which provides grid, data, linear solvers, preconditioners, distributed matrix and vector management, well modeling and visualization support. Based on this platform, a black oil simulator and a thermal simulator have been implemented. Benchmarks show that our parallel simulators are thousands of times faster than sequential simulators that designed for workstations and personal computers.
