There are two main problems in designing a 3D seismic survey. Firstly, a survey geometry needs to be established that will handle signal correctly—in terms of resolution and amplitude fidelity. Secondly, the same survey geometry must somehow effectively attenuate various types of noise that will be present. The design process described below achieves these two goals (record signal in an optimum way and attenuate noise as much as possible). The process may be applied to any 3D survey regardless of subsurface complexity and survey location. The method is applicable to land, marine, and OBC acquisition. Some example details in this...
