Rank SSA Filter for filtering random noise
Rank SSA Filter attenuates random noise on 2D or 3D seismic data using eigenimage decomposition and rank-reduction technique.
Noise Attenuation Tools
Rank Noise Attenuation Tools developed by Rocky Mountain Seismic Software is a kit of SeisSpace 5000.10 plugins for noise attenuation. The filtering approach is based on Singular Spectrum Analysis (SSA) or Cadzow technique for noise attenuation. Rank-reduction filters preserve signal amplitudes and are AVO-friendly.
Rank SSA 4D Filter works simultaneously in four dimentions
Rank SSA 4D attenuates random noise on seismic 4D data using eigenimage decomposition and rank-reduction. It is applied simultaneously in four dimension space (volumes, frames, traces, samples).
Ground Roll Filter for surface noise attenuation
Ground Roll Rank Filter attenuates ground roll and other surface wave noise.
Free tools
We offer it for free for all SeisSpace users.
Synthetic Ground Roll
This Synthetic Ground Roll tool is a simple generator of surface noise (like ground roll) for testing and demo purposes.
Despike
Despike is a simple tool for removing of random spikes from raw data.This filter applies cosine tapers and is deconvolution friendly. It is the same as automatic applications of multiple surgical mutes.
Smart AGC
Regular AGC (Automatic Gain Control) always blows up random noise before the first arrivals, while this AGC does not. The user does not have to pick up top mute to remove this noise.
