VSFusion VS3 System - Practical 3D VSP Processing |
|
|
|
VSFusion has designed and
integrated several component systems into the VS3SM 3D VSP
processing system to provide a superior image and rapid 3D
VSP survey turnaround.
The VS3 system focuses on:
- Detailed 3D pre-survey modeling
- Efficient and accurate data pre-processing
- Optimizing the velocity model for more accurate imaging
- Anisotropic Wave Equation Migration and 3-C-3D Vector
migration
- Flexible 3D image

Pre-Survey Design
The first priority in any 3D VSP project is to ensure
that the objective will be met by the acquisition
design. To accomplish this task, an accurate and
flexible modeling tool must be used to design the VSP
survey geometry. The VSFusion VS3 system utilizes the
GeoTomo LLC VECON system. VECON is a built-for-purpose
2D/3D VSP modeling system designed by VSFusion
geophysicists.
- The 3D model can be
quickly built using all types of available geologic
and geophysical support data.
- Source and receiver
geometry configurations are easily specified and
modified.
VSP Pre-Processing
Geocluster™ is the industry-leading comprehensive
seismic processing system designed and owned by
CGGVeritas. It contains hundreds of seismic processing
modules designed for 2D and 3D seismic processing. In
addition to these modules, Geocluster contains a full
suite of borehole seismic-specific processing modules.
Geocluster utilizes the speed of Linux PC clusters to
quickly run the most demanding seismic processing
functions. A full suite of analytical tools are also
available in Geocluster to extract the information
inherent within a 3D VSP, such as travel time maps, rock
property map sand inversion. Having access to
CGGVeritas’s extensive experience in 3D seismic
processing has allowed VSFusion to set up an extensive
library of job-flow templates. This allows us to apply
the proper processes to the data and easily manage large
volumes of data. This drastically cuts the cycle time
from raw data to reflection data ready for imaging. |
