Abstract

We are presenting results from a true-amplitude prestack depth migration in the angle/azimuth domain. The implementation is based on the generalized Radon transform. Working directly in the angle/azimuth domain means that we do not need to calculate any Beylkin-determinant, and multi-valued traveltimes, in the presence of caustics, are naturally unfolded allowing for true-amplitude results even beneath a complex overburden. Such an implementation has until recently been considered unfeasible due to the computational complexity for large 3D volume migration. Our implementation is made possible through a massively parallel implementation with fast access to large dataset.
