Pre-Stack and Post-Stack Data Compression and Its Impact on Seismic Attributes

With the multiplication of seismic data being generated each year for exploration and reservoir purposes, storage and management of pre-stack and post stack seismic files are still a challenge for infrastructure management. Even today, compressed seismic files make storage and management of large original volumes highly practical. At the end of the day, geoscientists and interpreters want to integrate all available data and, preferably, with the highest possible fidelity.<br>This work attempts to present the implications of compressing seismic files on both pre-stack and post-stack data analysis. First compressing methodologies are presented, and then a series of analyses of compressed volumes using different parameters were compared with original non compressed data. The results are discussed with examples.
