Abstract

In oil exploration, because of anisotropy of the earth, velocity of the waves in horizontal and vertical directions are not uniform; but we can apply the assumption with good accuracy in exploration procedure that in a layer, velocity changing is limited as a result of slow variation in density and elastic properties of the layers in this horizontal directions. In general, variation of above parameters in horizontal directions is very slowly than vertical directions. For this reason often divide acquisition area to smaller areas and ignore horizontal variations and apply same vertical velocity distribution in any sub-areas. Conventional formula for Bin size and migration aperture is based on constant velocity assumptions. In this paper calculation of Bin size and migration aperture for AHWAZ oil field is carried out base on linear model between velocity and depth. On the other hand Bin size and migration aperture have the firstorder effects on acquisition and processing cost, thus method of this paper steer to optimize and reduce the cost of acquisition.
