The Application of Non-zero Offset VSP Data in Oil and Gas Detection

The shot is located in some distance from well and the geophone is positioned inside the well to receive the seismic wave, the method is called VSP which belongs to 2D data acquisition.By data processing, P-wave seismic section, PS-wave seismic section can be attained and also the layer attribute can be extracted.Not only the oil and gas layer, but also the lateral distribution of it can be detected by synthetically analyzing P-wave section, PS-wave section and the layer distribution.
