A simulation was performed of the electromagnetic fields response to different unconventional reservoir scenarios and transmitter to receiver configuration, including strong anisotropy, combination of anisotropies and geometries, and larger monitoring times than conventional ones. The approximate solution of the anisotropic Maxwell equations was obtained using a mixed finite element method, discretized in space through the Nédélec spaces, combined with a leapfrog time stepping procedure. The results indicate: first, the signals have a long period; second, the magnetic field is the most sensitive field when discriminating different types of anisotropy for all receiver positions, the horizontal electric field does in the top and above the anisotropic layer and the vertical electric field does inside it; third, in both stratified and fractured medium the vertical electric field have higher total amplitudes inside the layer, the magnetic field in the top and inside it, and the horizontal electric field does in the top and above it, so, a receiver in the top of the formation could be advantageous; fourth, independently of the symmetry, the horizontal electric field is one order of magnitude higher than the vertical electric field above the anisotropic layer and this relation changes inside the layer; fifth, the conservation of currents in combination of anisotropies is preserved. Finally, in a horizontal well hydraulically fractured, the relative percent difference of the vertical electric field is higher than the other fields, but this relation can change when moving to other geometries like a T-shape fracture where the three fields have closer relative differences.

对电磁场对不同非常规油藏情景以及发射机到接收机配置的响应进行了仿真，包括强各向异性，各向异性和几何形状的组合以及比传统方法更长的监视时间。各向异性麦克斯韦方程的近似解是使用混合有限元方法获得的，通过Nédélec空间在空间中离散，并结合了跨越时间步长法。结果表明：第一，信号周期长；第二，信号周期长。其次，当区分所有接收器位置的不同类型的各向异性时，磁场是最敏感的磁场，水平电场在各向异性层的顶部和上方，垂直电场在各向异性层的顶部和上方。第三，在分层介质和破裂介质中，垂直电场在层内的总振幅较高，顶部和内部的磁场强度较高，水平电场在其顶部和上方的磁场强度较高，因此，在顶部的接收器编队可能是有利的；第四，与对称性无关，水平电场比各向异性层上方的垂直电场高一个数量级，并且该关系在层内部发生变化。第五，保留了各向异性的电流守恒。最后，在水力压裂的水平井中，垂直电场的相对百分比差异高于其他电场，
