Survey Data

For Curved Borehole Oriented Core or Curved Borehole Televiewer Traverses, the survey data is entered in the Survey Data tab in the Traverse Information dialog.

  1. Select the Survey Data tab.
  2. Select the Add button to add the required number of rows. This should equal the total number of survey readings for ALL Curved Borehole Traverses that you are defining.
  3. Enter the Traverse ID for each survey point. Traverse IDs entered in the Survey tab should correspond to those entered in the Traverse tab and Collar tab.
  4. Enter the Distance readings for the survey points.
  5. Enter the Trend / Plunge readings for the survey points.


  • The orientation format convention for Survey Data is always Trend / Plunge. This is equivalent to the standard Azimuth / Dip terminology commonly used to record borehole survey orientations.
  • The conventions used for Plunge (e.g., positive or negative) are determined in the Settings Settings dialogdialog, see below for details.
  • For multiple Traverses, data is entered consecutively in the ID, Distance, and Trend / Plunge columns for all Traverses.

Curved Borehole Options

For Curved Borehole Traverses, if you select the Settings Settings buttonbutton at the bottom of the Traverse Information dialog, the following options are available.


There are two options for defining the Plunge convention for Survey Data:

  • Negative = Down, Positive = Up
  • Positive = Down, Negative = Up

If you choose the Negative = Down option, then negative plunge values will represent the downward direction for the Survey Data.

If you choose the Positive = Down option, then positive plunge values will represent the downward direction for the Survey Data.

NOTE: This option only applies to Survey Data Plunge values entered for curved Traverses in the Traverse Information dialog. It does NOT affect the data conventions used in the main Dips spreadsheet.


For analysis purposes, curved borehole surveys in Dips are represented by a series of linear segments.

There are two possible de-survey options:

  • The Linear, at segment ends option, will directly connect the survey points with linear segments.
  • The Linear, at mid-points option, will assume each survey point is the mid-point of a linear segment, and generate the segments accordingly.
