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. |
