Seismic Acquisition Seismic Acquisition Pdf Reflection Seismology Migration cmp stacking gives incorrect image for complex subsurface structure. migration reconstructs a seismic section so that reflections are repositioned at their correct lateral location and reflection time depth. In this chapter, we will look at a basic processing sequence to obtain a seismic image from the raw seismic data, containing only re ections. the most important information that must be added to the data, is the seismic velocity. this is crucial for obtaining a proper image. A processing step which is important in putting reflectors in their correct location is migration. the need for migration is most evident when layers are not flat lying. Geologists, geophysicists and engineers who are unfamiliar with seismic acquisition and processing techniques and wish to learn about the steps involved in the acquisition of seismic data and the creation of subsurface images from this data.

Pengolahan data seismik darat atau laut serta latihan memilih parameter processing yang optimal untuk suatu kasus data menggunakan software pengolah data seismik yang umum digunakan dalam industri migas. In the following the complete processing of seismic reflection data is described including import of the seismic data (chap. i), crosscorrelation (optional for vibration data, chap.ii), setting the geometry (chap. iii), filtering the shot data (chap. iv), performing the velocity analysis and stacking (chap. v). It also explains the concept of seismic processing flow and deconvolution. the skill module also explains what the processors do to produce the seismic image. finally, we discuss the process of forming the seismic image by migration. there are several ways to migrate the data, including post‐stack, pre‐stack, time, and depth migration. The most common and versatile method used to image the subsurface is the reflection seismic method applied in either two dimensional lines or three dimensional volumes.
