APPLICATION OF WAVELET-BASED COMPRESSION

In this section, we discuss our testing of three datasets in different manners. We explore these datasets to investigate the different aspects of this compression algorithm. Specifically, the first is a 2-D synthetic shot gather contaminated by randdom noise. Using this example, we demonstrate how the random noise is removed from the shot gather. The second is a 3-D synthetic dataset consisting of many dipping reflectors. We show that making use of coherency will bring high compression ratio. The third one is a 3-D marine dataset which was recorded in the North Sea. In this example, NMO correction is applied before compression to improve the performance of this compression technique.
