Abstract

Summary

A forward model in time domain is presented to simulate the diffusion of 3D electromagnetic field generated by a source transmitter at the Induced Polarization method for oil reservoir exploration. We discretize the Maxwell’s Equations using the Yee Algorithm. An auxiliary field, which is coupled to Maxwell’s Equations to include the Induced Polarization effects, replaces the history depended quantities that are calculated instantaneously. In this novel approach, we use the analytical solution of a dipole in a homogeneous infinite space as boundary conditions in the mesh points around the source transmitter. Algorithm parallelization, adaptative mesh and time stepping are implemented to achieve fast computing. The error measurements confirm the effectiveness of the discretization scheme and the air-water interface model. Preliminary results focus on the transient state of the propagation of the electric field in a 3D multi-layered domain after the source transmitter is turned on and the relaxation time after the source is turned off.
