Curved Borehole Televiewer
The Curved Borehole Televiewer Traverse Type should be used when you have:
- A non-linear borehole with curvature defined by a survey file
- Joint orientations processed into true dip/dipdirection or strike/dip readings using televiewer or other method (e.g., processed oriented core)
The Curved Borehole Televiewer Traverse option allows you to apply the Terzaghi Weighting to joints measured on a curved borehole, by determining the orientation of the borehole for each joint measurement and applying the appropriate weighting factor based on the relative orientation of the borehole and the joint plane.
If you have unprocessed oriented core taken from a curved borehole (i.e., Alpha/Beta angles) then you should use the Curved Borehole Oriented core option rather than the Curved Borehole Televiewer option.

Traverse ID
For a Curved BH Televiewer Traverse, the default Traverse ID will have a "CBH-T" prefix (e.g., CBH-T1, CBH-T2, ...) when you initially add/create Traverses. After adding Traverses you can change the default ID values to any numeric or Alpha-numeric values.
Data Format
The Data Format options for a Curved Borehole Televiewer Traverse are the same as for a Linear Traverse.
- Dip/DipDirection
- Strike(Right)/Dip
- Strike(Left)/Dip
- Trend/Plunge
See the Linear Traverse topic for details.
Traverse Format
The Traverse Format for a Curved Borehole Televiewer Traverse is Survey File. The Survey File data is entered in the Survey Data tab in the Traverse Information dialog. See below for details.
