Abstract
Methods and apparatus are described for compressing seismic data. The data compression is achieved by splitting the data into subsets and applying requantization levels to those subsets which depend on a number representing the subset and on time. Further error criteria ensure that the error introduced by the data compression does not affect the data in a time window representing the listening time. The compression ratio can be improved by applying data encoding techniques to the subsets.
