Summary
When complex structures with large velocity contrasts are present, wavefield techniques can provide improved imaging (structure, amplitude, and phase) over the more traditional Kirchhoff integral methods. Wavefield techniques rely on two elements: firstly, an advanced acquisition design with complete azimuthal coverage; and, secondly, wave equation based prestack imaging methods. Together, these two elements offer improved seismic imaging in complex structural environments by better handling of multipathing, amplitudes and phase.
