Compute Locations

The Compute Locations option is available in Analysis menu in the Grid Data View. It allows users to automatically compute and populate the X, Y, Z columns for planar structures recorded along a borehole traverse.

In order to use the Compute Locations option, the following must exist:

• Borehole Traverse Type(s) (e.g., Linear BH Oriented Core, Linear BH Televiewer, Curved BH Oriented Core, Curved BH Televiewer) defined in Traverse Information dialog.
• Traverse column in Grid Data
• Distance column in Grid Data
• X, Y, Z columns in Grid Data

Compute Locations

To compute locations:

1. Navigate to the Grid Data View.
2. Select Compute Locations from the toolbar or Analysis menu.

The location of any measurement recorded along a borehole traverse is computed and the X, Y, Z columns are automatically populated for those measurements in the Grid Data.

Compute Locations Methodology

The X, Y, Z location is computed using the Borehole's path:

1. Start from the X, Y, Z point of the Collar Data tab.
2. Traverse along the length of the traverse in the orientation of the traverse:
   1. For a Linear BH Oriented Core:
   1. The orientation is defined by Orient 2 and Orient 3 in the Traverses tab.
   2. The length is defined by Total Depth in the Collar Data tab.
   2. For a Linear BH Televiewer:
      1. The orientation is defined by Trend and Plunge in the Traverses tab.
      2. The length is defined by Total Depth in the Collar Data tab.
   3. For a Curved BH Oriented Core or Curved BH Televiewer, the traversal is made up of one or more linear segments. For each linear segment:
      1. The orientation is defined by Trend and Plunge in the Survey Data tab.
         
      2. The length is defined by Distance in the Survey Data tab.
         NOTE: Note the Curved Borehole Options for the Plunge Options convention and De-survey Options for linear discretization.
3. Interpolate the X, Y, Z point along the traverse path at the Distance specified in the Grid Data column. Distance = 0 is at the Collar.
