Redatuming to Improve Hard Rock Seismic Data

Abstract

Land seismic data is generally distorted by complex wave propagation through the regolith. This distortion greatly impedes the standard processing and imaging methods. I try to address this by transforming the data into a dataset that would correspond to a virtual acquisition surface below the regolith. I describe, modify and test several such redatuming methods on synthetic data. These tests then inform my application of the methods to field data, which show promising results.
