Directional Survey
Directional surveys define the 3D trajectory of your wellbore:
  • Measured Depth (MD) - Distance along the wellbore
  • Inclination - Angle from vertical (0° = vertical)
  • Azimuth - Compass direction (0° = North)
TVD, Dogleg Severity, Northing, and Easting are auto-calculated.

​
Primary vs. Backup

  • Primary - Active survey used for calculations
  • Backup - Historical surveys for reference
Only one survey can be primary per well.

​
Creating a Survey

  1. Go to Well Details > Directional Surveys
  2. Click Create New Survey
  3. Enter survey name and date
  4. Check Is Primary if this is the active survey

3D wellbore
PetroBench displays interactive 3D wellbore trajectories. Rotate, zoom, and pan to inspect the wellbore path.

​
Troubleshooting

Check that your file has recognizable headers and numeric data.
Sort your file by MD in ascending order before importing.
Use standard names: MD, Inclination, Azimuth.
