Optimization of ٣D land seismic survey design

Acquisition obstacles are one of the greatest problems that can disturb ٣D seismic surveys, which change the geophysical parameters and increasethe cost of the surveys. Therefore determining these obstacles besides studying the methods of decreasing their impacts is of a great importance.This article studies ٣D survey design factors, introduces the optimum design pattern in a case study and explains the ways of optimizing a ٣Dseismic survey. This article also studies the obstacles in one of the Iran’s south western oil fields and describes the methods of handling them andsuppressing their effects in different stages of survey design. These survey designs have been analyzed in ٣ stages. Results of different analysesguarantee the reliability and efficiency of this method.
