ABSTRACT:
A method for compressing seismic data to reduce data storage and transmission requirements applies wavelet transforms to digitized trace sequential data obtained from plural arrays of multiple acoustic sensors. The wavelet transforms are applied in at least three dimensions, and, in the case of underwater exploration, four dimensions. The transformed data is ordered and quantized to increase the number of zero data values, and the quantized data is compressed using rim-length encoding and entropy coding. The entropy coded data is stored for later retrieval or transmitted to a remote location. The retrieved or received data is decompressed, dequantized and inverse wavelet transformed to construct a representation of the original data. The compression can be selected to be in excess of 100:1 to significantly reduce the data storage and transmission requirements without significant degradation of the reconstructed data.
