The Hod 3D multicomponent ocean-bottom seismic (OBS) survey was acquired to image the reservoir through a gas cloud. Data were acquired with shot lines both along the receiver cables (in-line or parallel shooting) and orthogonal to the receiver cables (cross-line shooting).
This gave us an opportunity to compare the seismic images produced from these shooting geometries to see if there is factual support for the rumors that parallel shooting results in better converted PS-wave images than orthogonal shooting. In the following we use the term C-wave for a wave that propagates as a P-wave from the source to the reflector...
