Adding and Removing Downhole Columns

How to add and remove downhole data columns

Adding and Removing Downhole Columns

You can add any column from any table. Columns can be duplicated so that different formats can be applied to display the same column data. You can also add composited fields, as well as fields which are computed by the application, such as sample length or desurveyed sample coordinates.

 

Adding a new column

  1. In the Logs window, click a table to select it.

  2.  Right-click and select Properties.

  3.  In the Log View Properties dialog, select theColumnstab.

  4. By theColumns in Viewwindow, clickAddto launch theColumn Wizard.

  5. In the Column Wizard, choose to add either a Data Column, a calculated System Field or an Axis Column, and click Next.


    Select Column Type

    To display

    Example

    Data Column

    All downhole sample data from all data tables e.g. grades and lithology codes.

    Use this column type to display any of the original data fields from the imported tables.

    System Field

    Computed field values like downhole depth, inclination, dip and coordinates of the desurveyed trace.

    Use this column type to graph, say, how the azimuth of the hole trace varies downhole.

    Axis Column

    Downhole axis fields.

    Depth, Elevation, Easting and Northing.

    The selected table does not have to contain the fields you wish to display: for example, by choosing the lithology table here, and a grade field from the assays table in the next step, a composited field is created in which the selected grade field is composited over the sample intervals defined by the selected table.

  8. Select one or more fields you wish to add using the same display style.

  9. If a composited field has been defined (the selected table does not contain the selected fields), select the Compositing Mode, Weighting Method and Compositing Parameters and choose Next.
