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.
