Patent ID: 7952960

Claim:
A method of seismic exploration, comprising the steps of: (a) collecting a seismic survey proximate to a subsurface exploration target, said seismic survey comprising a plurality of seismic traces imaging at least a portion of said subsurface exploration target; (b) collecting at least one VSP data trace from a well proximate to said seismic survey; (c) selecting one or more migration VSP data traces from said at least one VSP data traces; (d) selecting one or more weight VSP data traces from said at least one VSP data trace; (e) calculating a weight function from said selected one or more weight VSP traces; (f) forming at least one Green's function from said one or more migration VSP data traces; (g) migrating at least a portion of said plurality of seismic traces using said weight function and said at least one Green's function, thereby producing a migrated seismic dataset; and, (h) using at least a portion of said migrated seismic dataset to explore for subsurface resources within said subsurface exploration target.
