Many types of noise exist in seismic data both coherent and random. It may be artificial, such as rig noise, or natural, such as swell noise. There's equally many methods of noise attenuation. Often we can separate signal from noise by using alternate dimensions or ways of arranging the seismic data. Our experience lets us pick the perfect denoise options from the vast seismic toolbox at our disposal. Cleaner data means more accurate model building and clearer migration results.
SWANA is just one of our many noise attenuation algorithms. It provides accurate and responsive noise removal by automatically adapting to spatially-varying ground roll characteristics in 2D and 3D domains, giving improved results over fixed parameter techniques such as FK.
