They are based on our tutorial datasets, which in turn came from the New Zealand Government’s Ministry of Economic Development under the “Open File” System. While coherent noise is usually handled during processing of seismic data, mean and median filters are commonly used for random noise suppression on poststack seismic data, but tend to smear the discontinuities in the data. These methods are compared against a traditional “shallow tow” (8 m) cable depth and de-phasing processing flow. Since the RadExPro Plus program sorts the structural elements of the database alphabetically, it is reasonable to number the flows so that they would be displayed in an accurate logical sequence. can purchase separate chapters directly from the table of contents 2.2.
