Attenuating the seismic interference noise on three-dimensional seismic data by frequency-receiver-shot (f-x-y) prediction filters

Abstract

Encouraged by the potential prospects of oil/gas and gas hydrates, exploration activities in the marine environment have increased extensively. These seismic experiments however, result in contaminating the signal by interference noise which is generated due to neighbouring seismic vessels working in the same area. This noise in seismic reflection data may be substantially minimized by seismic interference noise attenuation technique. This technique utilizes frequency-receiver-shot (f-x-y) prediction filters to estimate the noise. The predicted filters can be applied in the f-x domain to remove noisy frequencies in seismic records. We have performed this exercise on a multi-channel seismic reflection dataset and the results indicate that noise from different sources has been successfully eliminated from the recorded datasets. Our study suggests that the f-x-y interference attenuation mechanism preserves the primary signal and eliminates the seismic interference in an efficient manner.
