Steering Migration with Diffractions in Seismic Exploration for Hard Rock Environments, in Proceedings of the 75th EAGE Conference & Exhibition incorporating SPE EUROPEC, Jun 10-13 2013. London, UK: EAGE.

Hard rock seismic exploration normally has to deal with rather complex geological environments. These types of environments are usually characterized by a large number of local heterogeneities (e.g., faults, fracture zones, steeply dip interfaces). The seismic data from such environments often have a poor signal to noise ratio because of the complexity of hard rock geology. In such situations, the processing algorithms that are capable of handling data with a low signal/noise ratio are essential for a reflection seismic exploration. In this paper we describe an alteration of the 3D Kirchhoff post-stack migration algorithm that utilizes coherency attributes obtained by the diffraction imaging algorithm in 3D to weight or steer the main Kirchhoff summation. We apply the method to a 3D synthetic model with a presence of high level of random noise; and test the algorithm on the 3D seismic volume acquired on a mine site located in Western Australia.
