Smart stacking: A new CMP stacking technique for seismic data

WebVelocity information is essential to both common midpoint (CMP) stacking and migration. CMP stacking provides the basis for conventional velocity estimation techniques in that, for a number of trial velocities, the stack response of a CMP gather is computed and displayed in the form of a velocity table. An alternative approach to velocity estimation makes use of … Webreceiver location. The number of traces in a CMP gather is the fold. The distance between source and receiver is the offset. Geophysicists make moveout corrections to shift all traces so that reﬂec - tions in a CMP gather appear horizontal at their zero-offset times. Then, in a process called stacking, they add together the traces in the CMP ...
