Practical equivalent offset processing

John C. Bancroft

The equivalent offset method of processing continues to be a practical and useful tool in the seismic industry. However, some users have reported problems with their implementations, such as being noisier in the shallower parts of the section, or the presence of some unexpected aliasing noise.

Three items for improving the results are presented; the first a parameter selection, the second is an algorithm feature, and third the possible inclusion of an antialiasing filter.
