N2 - We simulate advection-diffusion flow of tracers in fractured rock geometries. Voronoi tessellation generates polygonal patterns, which we then use to introduce fractures and obtain fractured geometry. The rock geometry is discretized using a scalable, in-house developed discretization software. Lattice-Boltzmann and random-walk particle-tracking methods are employed to obtain flow field and recover tracer behavior, respectively. Tracers are allowed to cross semi-permeable interface between fractures and matrix. In addition, tracers can have variable partitioning coefficients. The implemented numerical framework allows simulating field-scale tracer experiments designed to estimate residual oil saturation. Use of HPC platform is necessary to perform such simulations in three dimensions.
