WebA common midpoint gather refers to a. seismic traces acquired from a single shot b. seismic traces that are acquired with a constant source receiver separation c. seismic traces that have been moveout corrected with respect to a central geometrical location. WebThe hyperbolic moveout formulae for the common-midpoint gather are obtained from different Taylor series expansions of a particular parametric moveout surface defined in the multicoverage data space. Such a moveout surface involves three kinematic wave-field attributes of two hypothetical waves, which have to be determined by a coherency analysis.
