Advanced interpretation is a module for high resolution stratigraphic analysis. It includes complementary tools for sequence boundaries modeling, visualization with color blending and automatic geobodies extraction and provides a powerful way to exploit the stratigraphic information from the geological time model.


GeoCellular Grid

Building a geological model is a key step to understand reservoir properties and dynamic behaviour of fluids. PaleoScan™ enables to carry out all the different stages of the geomodeling workflow to create a static model such as building stratigraphic units from the RGT model, gridding the model with various patterns, populating cells with seismic facies or petrophysical properties.

  • Use RGT model to drive the geometries
  • Corner point grid generation with stair stepped faults
  • Seismic facies modeling
  • Upscaling of well/log properties


Watertight Model

A sealed geological model can be obtained by converting the Relative Geological Time (RGT) volume into a watertight model. This process is realized interactively using stratigraphic layers from the RGT volume. The sealed model is meshed in 3D, using these geological boundaries, where intersections between faults and horizons is managed. It can be used for various applications in geomodeling.

  • Interactive layering
  • Remodeling of faults and horizons

  • Creation of fault polygons

  • Allan diagram for analysis of sealing properties

Color Blending

Color Blending allows to decompose image in 3 different color channels and play with the image contrast. By assigning attributes or frequency decomposition to each channel, it drastically improves visualization and facilitates the imaging of geological events throughout the seismic.

Various blending methods are proposed, such as RGB (Red, Green Blue), CMY (Cyan, Magenta, Yellow), HSV (Hue, Saturation, Value), HSL (Hue, Saturation,Lightness).

  • Real time attribute and frequency blending
  • Apply to Volumes, Arbitrary lines and Horizons
  • Improve geological events imaging
  • 2D and 3D Display

Rock physics information measured or calculated from well log data can be propagated in the seismic volume. This module includes several propagation methods, based on the geological time model, and the relative and absolute coloured inversion process.

Well log information can be populated in the seismic volume using the geologic time model as guideline. Various methods of propagation, such as inverse distance, kriging and co-kriging, are proposed in an intuitive interface offering real time preview on surface or cross section along wells.

This unique workflow constrained by the geology has numerous domains of application such as seismic inversion, reservoir characterization, geological correlation, velocity model building and synthetic seismic generation.

  • Propagate well log properties guided by geological time model
  • Methods: inverse distance, kriging or co-krigingPredict rock physics distribution
  • Forward modeling (synthetic seismic generation)
  • Acoustic Impedance a priori model
  • Rock type Prediction
  • Interval velocity model generation
  • Real time preview
  • Intuitive and useful for Quantitative Interpretation applications

Various methods to manage and/or convert data from time to depth domain are proposed in this module such as interactive seismic-well tie with a comprehensive method, intuitive logs depth adjustment and real time seismic depth stretching. This process is involved in many applications for reservoir characterization and velocity modeling.

The PaleoScan™ data link is an essential module for users who wish to maximize benefits from their PaleoScan™ interpretation. Thanks to a plug-in extension, users can take advantage of PaleoScan™ functionalities by exchanging interpretation results directly between various platforms such as Petrel®*, OpenWorks ®** and GeoTeric®***. In just a few clicks, it enables seamless data exchange with PaleoScan™. Data are fetched from one application and sent to the other on-demand.
