“…Assuming that the source location of the rig noise can be obtained, Manin and Bonnot () propose to flatten the rig noise with time shifts corresponding to its travel time and attenuate it with multichannel filters. Based on this idea, researchers presented different approaches to improve the localization of the source locations.…”

Abstracts Unwanted interference noise often causes problems during seismic reflection data acquisition and processing. In this paper we present two novel data‐regrouping methods that enable improved shot‐to‐shot coherent interference noise attenuation in marine seismic data. The two approaches are based on line mixing and/or shot skipping: (1) for a 3‐D marine seismic reflection data acquisition which is typically carried out by shooting closely spaced parallel lines, we propose to mix the shot gathers from two adjacent sail lines to break up shot‐to‐shot coherent noise. This approach takes advantage of the fact that adjacent sail lines are usually acquired with a significant time interval, resulting in different types of noise; (2) for a 2‐D/3‐D acquisition, we propose an algorithm to skip and reorder the original shots to decrease the continuity of the shot‐to‐shot coherent noise. This approach could also supply more aperture data for the first or last shot from both sides, which is beneficial for the coherent noise removal at the edge area. After regrouping the original data, the coherent noise can then be further randomized or isolated by sorting and transforming to other domains, typically the common p‐shot domain where a random noise attenuation tool could be applied to identify and attenuate such noise. Field data examples confirm the effectiveness of the methods.

“…This problem had been recognized by Manin et al (1993) and a solution was suggested. Assuming that the coordinates of the noise source can be obtained they suggested flattening the data with static shifts corresponding to the travel times and suppressing the noise with existing multi-channel filters.…”

“…Recently, Fookes et al, (2003) and Warner et al (2004) suggested picking arrival times of the noise, and then calculating the position of the noise source from the travel times and the coordinates of the source and receivers. Once the noise source is calculated the corresponding noise is attenuated as in the method proposed by Manin et al (1993). More recently, a method called "Diffraction imaging" is used by Khaidukov et al (2004) with 2D surveys for separately imaging weak point diffractors and thereby helping interpretation of faults in migrated seismic sections.…”
