Seismic reflection data processing has several main stages, e.g. <br /> <br /> <br /> <br /> <br /> deconvolution, stacking, and migration. After stacking, seismic traces imaged <br /> <br /> <br /> <br /> <br /> subsurface position in time-domain as the result of traveltime. On several dipping <br /> <br /> <br /> <br /> <br /> geological condition, this section will represent the subsurface condition <br /> <br /> <br /> <br /> <br /> irrepesentatively because of the apparent dip, so it needs to be migrated. Process <br /> <br /> <br /> <br /> <br /> to move data position from zero-offset to true subsurface position called <br /> <br /> <br /> <br /> <br /> migration. <br /> <br /> <br /> <br /> <br /> Kirchhoff’s theory use amplitude summation on diffraction hyperbolae. <br /> <br /> <br /> <br /> <br /> The application on poststack data in time- and depth-domain tend to have <br /> <br /> <br /> <br /> <br /> different abilities. Many analyses said that depth-domain migration would give a <br /> <br /> <br /> <br /> <br /> better and more representative result so it will easily interpret. Choosing the <br /> <br /> <br /> <br /> <br /> value of migration aperture is a parameter that should be highly considered. <br /> <br /> <br /> <br /> <br /> Application of Kirchhoff’s theory to depth migration proved to relocate <br /> <br /> <br /> <br /> <br /> the reflector to true subsurface location more representatively than time <br /> <br /> <br /> <br /> <br /> migration; diffraction resolved well and reflectors relocated over their true <br /> <br /> <br /> <br /> <br /> subsurface position. Over- and undervalued of migration aperture would <br /> <br /> <br /> <br /> <br /> decrease the quality of migration data.
