Abstract
Acquisition parameters can be improved through forward modeling employing ray tracing theory. If previous information about a certain target area is available, and depending on the desired acquisition geometry, a 2D or 3D elastic earth model driven by the subsurface geology and structure can be constructed; and its seismic response compared with the available seismic information used to obtain the underlying structural interpretation. Such a model can be used to simulate wave propagation in the subsurface as a function of different parameters, allowing for the selection of the best cost-illumination acquisition design to improve seismic image quality.
