Abstract
The results of seismic survey and data processing of folded zone Zagros considered as pattern of acquiring data in high folded structure area. It is recommend to perform seismic survey using the 3D technique instead of conventional 2D in difficult seismic and geological conditions such as Zagros folded zones. Ray tracing modeling technology should be used in order to select parameters of seismic acquisition system that will allow to choose optimal parameters for the geological problems solution in specific geological conditions. Advantages of applying summation technology for the first Fresnel zone showed in a comparison with traditional approaches.
