Abstract

Acquisition Geometry Design forms an important aspect in Land 3-D Seismic Survey Design. Different Geometry Methods are used for getting the Coverage in areas with different Seismo-Geological Objectives. These methods differ in optimizing the Cost, available Inputs, Technical requirements and production rates for meeting the survey objectives. Swath geometries using Orthogonal ,Slant and Brick patterns of shot templates are generally preferred designs. In all these types of geometries, only a limited subset of the laid channels are activated per a shot salvo. On a production day, some number of active channels per shot salvo as per the design of the acquisition geometry are laid. Some channels are also laid as advance spread for an optimum production rate. These channels are activated while the active receiver template is
