A multi-physics and multi-scale system and process to simu late imaging of hydrocarbon
reservoirs using electromagnetic particles and electromagnetic tomography. Embodiments
are applicable towards flood-front mapping and hydraulic frac ture imaging. With respect to
flood-front mapping, coated nanoparticles (or their software representation) may be injected.
In case of fracture imaging, the contrast agents (or their software representation) may either
be injected as prop pants, fibers, or nanoparticles Suspended in the Solution.
