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
seismic
volume were visually integrated by a 3D visualization system
specially designed for VSP solutions. This study demonstrates the power of 3C
processing of multifarious VSPs to enhance images of subsurface images in a
reservoir region.
