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 Webb23 sep. 2024 · Taner MT, Koehler F, Sheriff RE (1979) Complex seismic trace analysis.
