Abstract:

This work describes Seismic Data Processing and Noise Attenuation in the Gumry area, located in the Melut Basin in the South of Sudan. The data used in this study consist of six 2D lines (about 133 km in total), which were acquired by Blue Nile Geophysical Company (BGC) in 2004. The authors process the 2D data at the Data Processing Centre of the Blue Nile Processing Company (PBC) in Khartoum – Sudan. Land seismic data contains strong and source-generated noise, which deferent techniques eliminate. We use a band pass filter to attenuate this noise without affecting the data. This filter adaptively exploits both characteristics of the lower frequency and the lower velocity and high amplitude of the coherent noise (ground Role and linear noise). The result shows that band pass filtering and other techniques effectively attenuate the noise from our seismic data. This result enhanced the final migration sections obtained by post-migration methods.

Keywords:
