Fracture is significant in fractured reservoirs. It’s crucial to estimate the fracture features in fractured reservoir exploration. The coherence method that measures the similarity degrees between multichannel data could depict the fractures via the seismic signal variation anomalies. As a distinctive time-frequency analysis method, EMD has a good adaptivity and time-frequency resolution. We propose a novel method combining coherence with BEMD to reveal different scale of fractures. Firstly, the seismic coherence data is obtained via the 3rd generation coherence method. Then the data is decomposed into different frequency band data with the BEMD method. According to the application for the real seismic data from a typical fractured reservoir, it is effectively proved that the method we propose is feasible to reveal different scale of the fractures.
