• 3D Visualization Module
Log Correlation Module Key Benefits
• Simple, organized top picking workflow (follow the 8 steps)
• Rapid picking of tops using large number of wells
• Ability to pick both down wells and across wells
• Preset Default Log Types for both digital and raster wells
• Tops with pre-assigned display colors

Directional Well Module Key Benefits
• Enhance gridded surfaces with repeated tops along horizontal
wellbores
• Quickly regrid Surfaces
• Plan horizontal wells and load drilling data
• Analyze horizontal well performance and post results

3D Visualization Key Benefits
• View 2D Cross Sections alongside 3D Boreholes, Logs, Tops,
and Grids.
• Rapidly build 3D Vis project using one button launch from
Directional Well Module.
• Maximize wellbore trajectories in 3D.
