Combining Fracture Detection Approaches
Arcis has the unique ability to compute and display multiple fracture attributes:
• Shear-wave splitting from converted wave data
• Azimuthal AVO and NMO from wide-azimuth P wave data
• Curvature from post-stack volumes

Marine 2D / 3D Processing
Clari-FiTM
The industry is increasingly recognizing the benefits of broadband
data. Broadband seismic provides greater richness of both robust low
frequencies - ideal for deep structure imaging and inversion stability, and
high frequencies - which aid temporal resolution.
TGS’ Clari-FiTM
is a proprietary three-step processing solution which allows
broadband pre-stack seismic data to be generated from conventionally
acquired seismic data, (i.e. using single sensor streamers towed at a
constant depth.)
Enhancing Deep Data
A focused approach on spectrum enrichment and denoise that sharpens
the overall image and raises confidence on interpreting deeper data. Useful
on both newly acquired data and in improving legacy data.
Noise Attenuation
A variety of noise types can be found within each seismic data set.
After analysis, these are removed using the proper method. TGS has a
complete suite of denoise routines that operate in different domains and
are efficient at removing:
• Swell noise
• Spike noise
• Seismic interference
• Linear noise
• Random noise
• Ship or stationary noise
Multiple Removal
Each project presents unique challenges for multiple removal. TGS’ range
of versatile multiple removal algorithms ensure that a solution can be found
for even the most challenging problem.
Techniques include:
• TAMETM
(3D SRME)
• SMELT (Stepwise Multiple Elimination by Linear Transforms)
• High-resolution Radon multiple attenuation
• Apex-shifted Radon
• Diffracted multiple attenuation
• Post-migration multiple modeling and subtraction

Regularization / Interpolation
Data regularization / interpolation is an essential step in the preparation of
data sets for pre-stack time and depth migrations. TGS offers a range of
regularization solutions including:
• Local frequency-wave number regularization (3D)
• Tau-P along dominant dips (3D)
• Wavefield downward continuation
Additional Pre-Processing Techniques
• Refraction statics, water column statics
• Survey merging
• Footprint attenuation - available as both pre-stack and post-stack
implementations
• Q compensation
• Spherical divergence corrections

Depth 2D / 3D Imaging
Depth Imaging
Arcis uses TGS’ depth imaging software, ImageZTM
, built upon extensive experience in high-end imaging with the most advanced computer power.
TGS provides industry leading migration algorithms, including Reverse Time (RTM), Kirchhoff Pre-stack Depth (KPSDM), Wave Extrapolation (WEM)
and beam.
TGS’ velocity model building tools include full azimuth ray-tracing tomography as well as anisotropic parameter estimation tools for Vertical Transverse
Isotropic (VTI) and Tilted Transverse Isotropic (TTI) media. TGS has developed interactive well-editing and calibration tools to tie the seismic velocity to
the vertical velocity from well information. Leading-edge anisotropy estimation tools and auto-picking routines are used to derive epsilon and delta (plus
theta and phi for TTI imaging) from the seismic or Vertical Seismic Profile (VSP) data where available.
Additionally, TGS offers velocity model building tools such as Delayed Imaging Time (DIT) scans and subsalt tomography for salt model refinement and
complex land data modeling.
Depth Imaging Key Capabilities:
• 3D PSDM algorithms to meet all imaging needs
• Kirchhoff pre-stack depth migration
• Beam migration (rapid testing of velocity
models and salt interpretation)
• Common shot (and common P) one-way
WEM
• Reverse time migration (FD and pseudo
spectral methods)
• Mirror migration (Kirchhoff and RTM)
• Q Tomography
• Q Migration
• Full Waveform Inversion (FWI)
• RTM & Kirchhoff surface referenced for land
depth projects
• Tomography and Subsalt velocity model building
tools
• Full azimuth ray-tracing tomography
• Fault constrained tomography
• Simultaneous inversion for velocity, delta
and epsilon
• DIT Scans (RTM or WEM)
• Interactive beam migration and layer-
stripping RTM for salt model refinement
• Variable salt (dirty salt) velocity modeling
and updates
• Specialized Model Building Tools
• Interpretation driven modeling
• Directional imaging stacks (for WAZ data)
• 3D RTM gathers for tomography updates in
complex areas
