Abstract

Reverse-time migration provides a structural image by correlating forward and reverse-time wavefields. Finding amplitude-preserving migration weights can be a challenge if the Green functions used for imaging were not stored. As an alternative, we used a newly developed iterative solver for 3-D frequency-domain finite-difference wave-propagation modelling to estimate migration amplitude weights at just a single frequency. We applied this approach to two complex synthetic examples.
