Wave Selection in High Definition Seismic Technology Based on Method of Projection on Valid Parameters Domains

The problem of qualitative selection of useful waves at presence in the VSP data essential regular and irregular noises is one of the basic problems in high definition seismic data processing. Use of method of projection in the valid parameters domains at selection increases a noise stability and detail of selection results. Methodical questions and features of realization of wave selection based on application of a priori model of medium for VSP data containing a different kind of frequency noises are considered in the paper. The example of method application in selection of offset shot point VSP data is given.
