The movie shows fractional flow of oil and water in a generic water-wet porous medium. The and the water are invisible and the oil phase is shown by a color
encoded surface. The color represents the pressure distribution, where red is
high and blue low pressure. The porous medium is resolved by 250^3 grid
points. Water and oil are injected at a fixed rate and the system approaches steady conditions.

Ingrain's digital rock physics lab computes the physical properties and fluid
flow characteristics of oil and gas reservoir rocks. Our technology leads the
industry in measuring shales, carbonates, tight gas sands and oil sands.
Ingrain uses advanced lattice Boltzmann methods to simulate multiphase flow
in the rocks (porous media). The simulations are accelerated by using
GPUs and the CUDA technology by two orders of magnitude compared to a state
of the art multicore desktop computer. On a single Tesla GPU with 4GB memory
we are able to simulate medium-sized problems (up to 800^3). For larger grids
multiple GPUs are used in parallel.
