This section contains modules for performing seismic stacking operations. Stacking combines multiple traces from a CMP (Common Midpoint) gather into a single trace, enhancing signal-to-noise ratio by summing coherent reflections while attenuating random noise. Stacking is a fundamental step in seismic data processing, carried out after NMO correction and, if required, after muting and velocity analysis.

Available modules include: CMP common offset stack, Fast stack, HVA stack imaging, Horizon picking, Horizontal velocity picking, Precompute VA, Progressive stack, Stack, Stack Imaging, Stack imaging (obsolete), and Stack imaging multi.
