Towards the implementation of a low frequency electromagnetic induction tool for propped fracture diagnostics, it is necessary to examine the method’s applicability to fractures of realistic features. We rely on a fast Fourier-transform-based volume integral equation simulation method for forward modeling to simulate realistic fracture geometries formed due to effects present in actual formations. Improved performance is achieved by removal of model features that are of little significance to the results and yet cause a significant computational overhead. To properly account for the effective proppant conductivity, a new technique for the measurement of proppant conductivity using a resistivity core holder is proposed. The conductivity of petroleum coke—a potential candidate to be used in the field—is lab-tested. The resulting values are used for the forward simulation of the tool’s response to the various fractures. Distinct results are obtained for fractures with different proppant distributions, indicating the possibility of distinguishing between them using a future inverse solver.
