Among them, low frequency data plays a particularly important role in the inversion. From the perspective of acquisition, the application of low-frequency sources is an effective means to obtain low-frequency data from the source. In terms of processing, special processing techniques can also boost low-frequency components in seismic data, such as deghost process for variable depth streamer data, seismic envelope Full-waveform inversion and deep learning. During the inversion process, an effective low-frequency data can reduce the dependence of low-frequency models from logging data, it will reduce the multiplicity of inversion results, and improve the accuracy of inversion.
