VSFusion analysts utilize
two leading software packages for borehole seismic
processing
SeisLink
SeisLink™ interactive VSP processing suite is used for the
majority of VSP processing from simple checkshots to 2D
Walkaway VSPs. The interactive software design eases input
of various data types, including surface seismic and log
data, with outputs to a plotter or to an industry standard
CGM format. |

Functions unique to borehole
seismic processing, such as wavefield alignments, linear
depth displays, and multicomponent displays, are fully
integrated components of the SeisLink system. 2D
sparse-spike inversion is one of many special tools in
built into the software. System capabilities include, but
are not limited to:
- Checkshot surveys
- Well-log editing and calibration
- Synthetic seismogram
- Zero-offset VSP
- Offset/multioffset VSP
- Walkaway VSP
- Multicomponent VSP
- 3D VSP
- AVO modeling and analysis
- 1D, 2D & 3D acoustic impedance inversion
- Fracture analysis
- Microseismic analysis
- Wavelet extraction
- Tau-P processing
GeoCluster
GeoCluster is a comprehensive seismic processing suite
built around clusters of PC type CPUs and has enormous
processing capabilities. CGGVeritas uses the system for 3D
and 4D surface seismic processing and analysis. Large
borehole seismic datasets, including 3D VSPs, are loaded
into the GeoCluster system for batch processing,
facilitating fast turnaround. A full suite of analytical
tools are available with 3D VSP data from inversion to 3D
visualization. Processing within a Linux™ environment
means portability, enabling VSP processing to be performed
at virtually any location. |
