A robust method for 3D noise attenuation

Attenuation of multiple diffractions using a cascaded noise removal sequence

“…The process of noise removal using a 3-D weighted slant stack (NS3D) is documented in Martinez et al (2000) and Martinez (2003). In brief, a sub-volume of a given dataset is transformed using a 3-D weighted slant stack (where the weights are, in general, smoothed inverse power of trace amplitudes) and then inverse transformed to an output trace at the centre of the volume.…”
