Directional Surveys

Import and manage wellbore trajectory data in PetroBench. Upload directional survey files, visualize well paths, and use survey data in rod pump simulations.

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

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

Adding Points

Click Add Point:

Field	Range
Measured Depth	Increasing values (ft)
Inclination	0-90°
Azimuth	0-360°

Enter points from shallowest to deepest (increasing MD).

Vertical Well Example

MD	Inclination	Azimuth
0	0°	0°
[TD]	0°	0°
