GeoCenter offers seismic data compression using discreet wavelet packet transforms. Our compression algorithm has the following features:
• Fast 1D and 2D compression
• Ability to sort compressed data sets.
• Improved random access times for large data sets
• Ability to compress data to disk or tape
• Compression fully integrated within our internal data format
Frequently raw land shot records can contain spikes and high amplitude anomalies. With competing multi-trace compression algorithms, this type of data can become corrupted by the compression. By using GeoCenter's 1D compression algorithm, the damage can be minimized.
