Seismic data high resolution processing technique and its application

With the oil-field exploration maturity increasing, seismic data interpretation requires better imaged data from processing and higher field quality data from acquisition. The routine seismic data processing techniques can hardly meet the needs of high resolution seismic data processing and interpretation, as a result seismic data have to be processed with new high resolution processing workflow. Regarding the characteristics of the local seismic data and the oilfield E&P requirements, high precision static correction, high-fidelity de-noising, amplitude-preserved processing, wavelet consistency and high precision velocity analysis and imaging and other techniques were suggested in this paper. Those new techniques were used in the seismic data processing for the old data, as a result the fidelity, signal to noise ratio and the resolution for the old processed data were greatly improved, the satisfied results were achieved.
