Abstract
Full-wave 3D seismic surveys are designed for the simultaneous recording of the full seismic wavefield, including compressional (P) and shear (S) wave propagation modes. In most marine cases, the seismic source energy is provided by P-wave acoustic sources towed in the water column with pressure and threecomponent particle motion sensors deployed on the sea floor for recording P-wave and converted-wave (PS) reflection data. With the sensors deployed on the sea floor, they are typically decoupled from the source, allowing very flexible survey design options, similar to those used on land. Geophysical and operational characteristics of four general classes of marine full-wave 3D survey design are discussed and compared in this presentation: Parallel, Orthogonal, Line Patch and Node.
