Seismic signal is a complex non-stationary signal with a definite frequency bandwidth, and the waveform is affected by all the frequency components in the band. So a new method for reservoir prediction combined empirical mode decomposition with generalized Hilbert transform is proposed. The empirical mode decomposition (EMD) technique adaptively decomposes the seismic signals into a series of intrinsic mode functions (IMF), and every IMF component is carried out the GHT calculation. By comparing the results with reservoir development in fixed wells, the IMF components sensitive to the reservoir are optimized and used to carry out reservoir prediction. The computational result of actual data shows that the method based on EMDand GHTcan be used to describe the reservoir accurately.
