BEAMFORMING IN SEISMIC DATA PROCESSING

Minimum variance unbiased (MVU) beamforming is a type ofmultichannel filtering which extracts coherent signals without distortion, whilstminimizing residual noise power. Adaptive beamforming estimates signal and noisecharacteristics as part of the extraction process. This paper gives the fundamentalprinciple of beamforming including signal and noise model, design criteria and theobtained beamformer. The adaptive beamformer used here is designed from models ofprimary and multiple reflection signals having parametrically specified moveout,amplitude and phase variation with offset (MVO, AVO and PVO). However, PVO isnot usually jushfied in practice. The resulting analysis provides data for input intoAVO and PVO schemes for obtaining lithological information. Synthetic data examplesillustrate details of implementation of parametric adaphve MVU beamforming and theresponse characterishcs of the resultaflt design. Real data examples show thatdata-adaptive beamforming is more flexible and more effective in attenuating multiplesin prestack common mid point seismic data than Radon transform methods. Incommon with other prestack multichannel processes, the advantages of beamformingare shown to best effect in data with a good signal-to-noise ratio.
