Query: Numerical Simulation of Multi-phase Flow in Porous Media on Parallel
  Computers   A parallel reservoir simulator has been developed, which is designed for
large-scale black oil simulations. It handles three phases, including water,
oil and gas, and three components, including water, oil and gas. This simulator
can calculate traditional reservoir models and naturally fractured models.
Various well operations are supported, such as water flooding, gas flooding and
polymer flooding. The operation constraints can be fixed bottom-hole pressure,
a fixed fluid rate, and combinations of them. The simulator is based on our
in-house platform, which provides grids, cell-centred data, linear solvers,
preconditioners and well modeling. The simulator and the platform use MPI for
communications among computation nodes. Our simulator is capable of simulating
giant reservoir models with hundreds of millions of grid cells. Numerical
simulations show that our simulator matches with commercial simulators and it
has excellent scalability.
