This directory contains the 2004 BP Velocity-analysis Benchmark dataset, as seen at the workshop ``Estimation of Accurate Velocity Macro Models in Complex Structures'' at the 2004 EAGE meeting in Paris, France. Here is a reverse-time migrated image of the dataset, courtesy GXT.
The SEG is merely helping to distribute this dataset. By downloading this dataset you agree that the SEG is not liable in any way because of that assistance.
Files ending in ``gz'' have been losslessly compressed using the UNIX command ``gzip --best''.

Note the main data files are about 1 gigabyte in size apiece. When uncompressed, they will be just under 2 gigabytes in size (so that they can be stored on file systems that do not support individual files larger than 2 gigabytes in size). These files may take an hour or more per file to download! Please avoid attempting to download these files during peak network traffic times, and consider obtaining the dataset by disk-to-disk copy from someone who already has the dataset instead of by download from this site.
