Service: 3D VSP
Both 2D and 3D VSPs improve reservoir characterization.
High-resolution VSP data can be integrated with surface
seismic data to provide detailed descriptions of formation
properties and identification of reservoir compartments
not possible with surface seismic data alone.
AVO and Anisotropy
Modeling and Analysis
- Surface seismic AVO
calibration
- Anisotropy detection
for accurate model building
- Better understanding
of lithology, porosity, pore fluids, and orientation of
aligned fractures

Benefits and Applications
Reservoir Delineation
-
Depth prediction of
seismic events ahead of and offset from the drill bit
-
Time-depth correlation
with surface seismic data
-
Structural imaging
-
Improves reservoir
characterization by delineation of faults and pinchouts

3D VSP Imaging, and
3-C, 3D Migration
- Simultaneous surface and borehole seismic data
acquisition reduces operating costs
- Improved vertical and lateral resolution compared to
surface seismic
- Using a shared VSP calibrated velocity model, the 3D VSP
can be integrated with the surface seismic data
- Volumetric estimates improved by high resolution 3D VSP
- True 3D migration in time and depth
- 2D out of plane migration errors solved by 3D migration
