Although three-dimension (3D) surface seismic can provide images of subsurface structures with certain accuracy borehole seismic survey is critical important to improve the images in a reservoir region with high resolution using three-component (3C) geophones placed in a well bore. In this paper, we applied 3C VSP processing techniques to one zero offset and 6 offset VSP (Vertical Seismic Profiling) data at different azimuths to enhance the subsurface structure images from 3D surface seismic.
This VSP survey
was acquired from a vertical well in an oilfield in northeastern
