system and method for speed anomaly analysis

摘要

summary “system and method for velocity anomaly analysis” velocity model analysis methods include defining velocity anomaly models for a subsurface region under study. The velocity anomaly model is superimposed on a seismic stack image to produce a hybrid velocity / amplitude model. Regions in which stack amplitudes coincide with velocity anomalies can be interpreted as representing structures of interest. In one embodiment, clathrate deposits are identified using the hybrid model. In one embodiment, geobodies are identified and velocity anomalies are restricted by geobodies to review migration models.
