Abstract
B026 Application of Pre-stack Wave Equation Depth Migration in North West Europe Introduction 1 Travel-time based PreSDM methods are known to only image only part of the wavefront in the presence of high velocity layers or complex/rugose structure. For such environments in the Gulf of Mexico and more recently offshore Angola wave equation PreSDM has proven to be beneficial yielding significantly improved imaging. The technique has also been applied in the North Sea and North West Europe. We present and discuss case studies from the latter comparing and contrasting our observations with results from standard 3D Kirchhoff PreSDM. Method The
