WebJan 16, 1990 · In dip-moveout (DMO) processing, the seismic velocity is often assumed to be constant. While several approximate techniques for handling vertical velocity variation have recently become available, here the authors propose a method for computing the kinematically exact DMO correction when velocity is an arbitrary function of the depth. WebWe propose a new Cross Dip Moveout (CDMO) correction for crooked-line binned reflection seismic data. First, an optimal slalom/curved processing line that best fits the Common …

Hyperbolic stacking over offset may be the most important computer process in the prospecting industry. It is more important than migration because it reduces the data base from a volume in (s,g,t)-space to a plane in … WebDec 3, 2014 · Dip-moveout correction (DMO) is needed to correct for the dip effect on stacking velocities and thus preserve events with conflicting dips during CMP stacking. …
WebConventional imaging methods, e.g., normal moveout (NMO)/dip moveout (DMO)/stack or pre-stack migration, require a sufficiently accurate macro-velocity model to yield appropriate results, whereas the recently introduced common-reflection-surface stack does not depend on a macro-velocity model. For two-dimensional seismic acquisition, its ...
