N2 - It has been done the study of reducing NMO residual on medium anisotropy in Field "X" by using Fomel and Stovas method. The anisotropic medium affected the seismic prestack of near, mid, and far offset when the NMO correction was being conducted. The correction principally used the isotropic medium approach where the seismic event often encountered problems in its far offset. The problem was the seismic trace appearance in form of hockey stick and NMO-stretching. The purpose of this study is to understand the best residual value of travel time by Fomel and Stovas, Alkhalifah, and conventional hyperbolic methods. The semblance analysis was usedlongside all three methods to obtain the value of V nmo and anisotropy (η). The values were then compared. The result shows that the non-hyperbolic Fomel and Stovas method is better in reducing residual NMO as indicated by the smaller residual value compared to Alkhalifa and conventional hyperbolic methods of travel time. The small residual contributed to eliminate the effect which was caused by anisotropy medium like hocky stick effect.
