CRP stack along layer

Abstract

Amplitude preservation has long been an important issue in seismic processing, great progress has b een taken to satisfy the demand of seismic exploration especially for structural formation, but for lithologic prospecting, there still exist some traps such as stretching effect in both NMO and migration, CDP scattering e ffect in CMP of dip reflection, dispersion as well as smearing effect in migration, and so on. To settle these effects on reflection, a technology called Tracing Reflection Along Layer (TRALayer) is designed to gather traces with same CRP (Common Reflection Point), by which an one by one relationship between reflector point and reflection is established and Snell's law is stand. CRP gather is acquired by TRALayer, it could be used to accurate AVO inversion; CRP stack is acquired by TRALayer, and it could be used to precise
