Interferometric imaging of VSP data requires only local velocity knowledge and avoids the effects of the complex overburden. We compute virtual source gathers, synthesizing the data that would be recorded if sources were located in the borehole along with receivers. We demonstrate the importance of having adequate offset range in surface shots, to provide a range of illumination angles and capture events such as scattering off the salt flank. These data can be imaged using a variety of… CONTINUE READING
