f 3D Concentric circle survey - Processing for steep dip imaging

Optimal imaging of reflection energy in steep dip structural environments requires that the data be acquired and processed in a way to retain, and position (migrate) the seismic reflection information. In certain structural situations, such as salt diapirs, special acquisition geometries can be employed which substantially contribute to the overall goal of enhanced imaging of the subsurface . However, these acquisition geometries can cause unique problems in the subsequent processing of the data. Overcoming these difficulties and producing a high quality product requires retention of steeply dipping energy throughout the processing sequence, specially adapted seismic processing techniques, integration of prior knowledge and a degree of creativity.
