Pluri-Gaussian Simulation is a method for simulating facies properties while respecting inter-facies relationships defined in a bivariate Gaussian Truncation Diagram (TD). In addition to providing the fully integrated PGS method for Facies Modeling in Petrel, the plug-in also features the Truncation Diagram Editor offering a complete and user-friendly toolbox to create TDs.
  • Performing efficient facies simulations
  • Method fully integrated in the Facies Modeling process
  • Conditioning to upscaled cells
  • Imposing non-stationarity (locally varying facies fractions)
  • Honoring locally varying variogram range and orientation
  • Respecting inter-facies relationships as defined on the Truncation Diagrams (TDs)
  • Accepting different TDs per regions for one variogram
  • Drawing TDs manually via a complete toolbox
  • Building TDs directly from hard data
  • Adjusting TDs automatically to target fractions
  • Visualizing TDs and statistics
PGS allows to efficiently simulate lithologies while respecting: conditioning data, inter-facies relationships (ie Truncation Diagram) and non-stationarity (locally varying proportions and variogram range and orientation). Furthermore, the Truncation Diagram Editor provides convenient tools to create TDs either manually (by drawing limits and zones) or automatically (initialized from hard data).
