PaleoScan™ Core is the new generation of seismic interpretation platform. It includes all the necessary tools for a complete interpretation workflow, for data I/O, horizon and fault interpretation, rapid data screening and navigation in a fully integrated 2D and 3D environment, running on Windows®.

  • Integrated 2D and 3D seismic environment
  • Rapid data screening
  • Horizon, fault interpretation (picking, tracking, mapping)
  • Well/log management, culture data, etc
  • Parallel computing with latest multi core technologies
  • CPU/GPU acceleration
  • Multi survey and session management




This method uses a comprehensive approach which consists of a three-step computer aided workflow. Our algorithm first tracks first every possible horizon within the seismic volume and assigns relative geological ages automatically. Then the interpreter edits the relationships between horizons and updates the model in real time to obtain the optimum solution. Based on the horizon grid, a geological time volume is computed from the seismic.

  • Global method, semi automatic
  • Geological Time model generation while interpreting
  • Manage peak, trough, zero crossing and inflection points                    
  • Multi scale (exploration to reservoir)
  • Manage fault/horizon intersection
  • Fast and interactive
  • Real time model preview




The Relative Geological Time (RGT) method is now adapted to 2D seismic lines. A 2D horizon patch grid is created over multiple seismic lines. Thanks to a user friendly interface environment, multi 2D lines can be interpreted in a comprehensive way using an innovative workflow. Mis-ties effect between the lines are managed by computing a global variant shift function.

  • Single and multiple 2D interpretation
  • Mis-tie correction with dynamic shift
  • 2D Model-Grid, 2D Geomodel, 2D Horizon Stack
  • Horizon picking and 2D tracking
  • Pseudo 3D Geomodel creation



Interpret quickly and accurately various type of horizons. In addition to all classical tools for traditional horizon interpretation, an unlimited number of horizons, also called "horizon stack", is derived from the geologic time model to explore seismic volumes beyond the seismic resolution.This horizon slicing is widely used for data reconnaissance, detection of prospect leads and comprehension of reservoirs at a fine scale. A flattening option on horizon is also available.

  • Interactive auto-tracking
  • Powerful editing options
  • Horizon stack generation
  • Attribute mapping
  • Full volume stratal slicing


Thanks to interactive picking tools, fault patches can be quickly picked and merged in a semi automatic workflow by filtering according to azimuth and dip. Combined with structural attributes either based on the seismic or the geologic time model, subtle faults and fractures can be imaged and interpreted in 3D.

  • Fast and interactive tool to optimize fault interpretation
  • Semi automatic merging/splitting of fault patches
  • High resolution throw mapping
  • Fault viewer with cross navigation
  • Fault detection from geomodel curvature
  • Dip/Azimuth filtering



Slicing through the horizon stack becomes a simple and very precise way to identify geological events and potential prospect leads. Depositional features like channels, incised valleys, turbidites fan complexes, etc. can be easily tracked. Geological features can be delineated either manually or automatically with simple and intuitive contouring tools. Quantification tools, such as volumetrics or measurements of spatial extension, are also available to assess potential targets.

Attribute and isochore mapping can be performed to analyse rock physics distribution.

  • Extract geobodies from stratal-slicing
  • Automatic or manual contouring
  • 3D modeling of bodies
  • Editing/smoothing options
  • Volumetrics computation
  • Attribute and isochore mapping






A large panel of attributes can be obtained either on volumes or surfaces to reveal stratigraphic and structural events. Denoising tools are also available to condition the data. A cross comparison can be performed by using interactive co-rendering data and synchronised views. Calculator with real time preview, frequency filtering are also available.

  • Reveal stratigraphic discontinuities
  • Fault Enhancement
  • Frequency filtering
  • Surface and volume attributes
  • Real time computation





Spectral Blueing method helps the interpretation of seismic areas with too low amplitude values. It is a quick technique which can be easily applied on seismic data and improves the vertical resolution of seismic volumes. Following the same workflow as Coloured Inversion, this method is based on reflectivity time series computed from acoustic impedance well logs. It defines an operator used to increase the vertical resolution of seismic data.

  • Average seismic spectrum estimation
  • Wells reflectivity spectra in a log/log scale
  • Wells impedance spectra in a log/log scale
  • Fitting of a trendline through these spectra

Inversion of seismic data to acoustic impedance often requires time and expertise. Despite the benefit of such a process, inverted data are only used in a limited number of cases. To overcome this, Coloured Inversion is a quick technique which can be easily applied on seismic data and performs a simple understandable inversion process.

Build interactively a geological correlation panel across well log data, at any location along the trajectory by slicing horizons and creating 3D geological layers. Well tops and horizon interpretation are checked and vertical differences automatically quantified in an interactive table. Fine well to well correlation can be done with the horizon stack, in both depth and time domains. Flattening options on markers or horizons are also available.

  • Interactive display of logs and markers
  • Correlation of logs using the horizon stack
  • Well markers QC table
  • Highlight well-seismic miss-ties




Interactive cross plotting of attributes is a fundamental tool for rock type classification, AVO analysis and understanding fluid substitution effects. Comprehending the intricacies and selection of attributes is essential for successful reservoir analysis in quantitative interpretation

  • Cross plotting of volumes
  • Interactive facies classification
  • Automatic classification using SOM and K-Mean
  • Applied on horizon and horizon stack
  • Geobodies extraction
  • Facies volume generation







Spectral decomposition is an innovative technique relying on the transformation of each individual 1D seismic trace, into a 2D time-frequency representation using Short Time Fourrier Transform (STFT) or Continuous Wavelet Transform (CWT). It provides high resolution imaging of reservoir detail, geological discontinuities and produces very informative maps of thin beds, especially in clastic successions with sharp impedance contrasts.
