New Features

Why it Matters

Enriched petrophysical functionalities  
  • Interactive creation and editing of trend lines in Pore Pressure Prediction workflow 
  • Coefficients for empirical compaction trend computations in Pore Pressure Prediction are automatically determined
  • Automation of manual tasks enables quick look workflow to reduce time to results
  • Dynamic contractor charts on Xplots
  • Easier to find appropriate correction charts and to add new charts
  • New comprehensive zonation picking tool tool to create and use a catalog of zone properties (name, color, pattern, description) when picking intervals or zones in layouts.
  • Streamlines visual picking of zones and features
