Summary We started TFEM exploration at the beginning of 1990s. So far, we have completed hundreds of projects, mainly used in the oil and gas predication from complex fault-block, deep burial hill, stratigraphic trap and recognition of volcanic rocks. From the beginning of 2012, together with new technologies such as seismic constrained inversion, holographic integrated interpretation, etc., the lateral and vertical resolution of TFEM data has been greatly improved, and this produces good exploration results and greatly increases the success rate of pre-drilling predication.
