PERBANDINGAN PENCITRAAN PENGOLAHAN DATA SEISMIK METODA KONVENSIONAL DENGAN METODA CRS (COMMON REFLECTION SURFACE)

The main purpose of seismic exploration method is to increase the signal-to-noise
ratio for ease of identifying the boundaries of rock layering and provide imaging
geological model as closely as possible to the real situation. Therefore, each stage
of processing has a very important role. One of these stages is stacking. Stacking
has long been used in seismic data processing. Although the general trend of the
moment, the data processing methods began to shift toward pre-stack imaging,
stacking is an important step in seismic data processing, because the cross section
of the stack is the initial intrepertasi subsurface imaging. Some new methods are
developed to improve the stacking method that has been used for this, one of
which is the Common Reflection Surface stacking method. By processing the data
using this method can be seen geological structure model and limit its apparent
bedding rock compared to the conventional method of processing seismic data.
