There is often a high expectation for electromagnetic (EM) method to identify hydrocarbon target, especially in geologically complex areas. To meet such challenges, we have developed the time-frequency EM method. In the paper, a new way of data processing, constrained inversion using logging-seismic model, is developed and discussed, which is used to build the resistivity and polarization models. Some examples are illustrated to present the major functions of TFEM method is directly to detect the hydrocarbon reservoir.
