• 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

• 3D Visualization Module

Cross-Section Module Key Benefits

• Display deviated and horizontal well bores

• Pick tops on deviated and horizontal wells using digital logs

• Rapid well top editing using Smart Pick

• Rich posting functionality (well data, test indicators, production

charts, etc)

• 3D Visualization Module

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.
