WebbThe ideas of 1-D complex seismic trace analysis extend readily to two dimensions. Two‐dimensional instantaneous amplitude and phase are scalars, and 2-D instantaneous frequency and bandwidth are vectors perpendicular to local wavefronts, each defined by a magnitude and a dip angle. WebbThis is done through a process called binning, by dividing the 2D line range or the 3D survey area into a number of equal-sized CMP bins and, for each bin, collecting those traces whose midpoints fall within the bin as the CMP gather of this bin. The number of traces, or midpoints, within each CMP bin is called the fold. As an important seismic
