Random noise attenuation by using FDNAT filter on seismic data in east Diwaniya, South Eastern-Iraq

الملخص EN

The frequency dependent noise attenuation (FDNAT) filter was applied on 2D seismic data line DE21 in east Diwaniya, south eastern Iraq to improve the signal to noise ratio.

After applied FDNAT on the seismic data, it gives good results and caused to remove a lot of random noise.

This processing is helpful in enhancement the picking of the signal of the reflectors and therefore the interpretation of data will be easy later.

The quality control by using spectrum analysis is used as a quality factor in proving the effects of FDNAT filter to remove the random noise.
