Optimization of acquisition parameters is very critical step of 3D survey design as it affects quality of subsurface image, productivity and cost of seismic data thereby fulfillment of assigned objective. Exploration requirement, at times, have multiple targets lying at different levels ranging in depth from very shallow to deep. Since the parameters are objective oriented, such areas of multiple (multi level) objectives pose great challenge to the survey designer. The situation could be multiple targets with higher resolution at shallower and deeper levels, or recognition of weak events at deeper level as well as higher resolution at shallow level or high / low velocity layers or anisotropic media in a confined.
