  1. questionVIDEO TUTORIAL: Displaying downhole data on drillhole cross sections.
    A detailed demonstration on the display of your downhole data (e.g. assays, lithology, regolith, geophysics, etc) on drillhole cross-sections: Additional tutorials can be found on the MapInfo youtube channel, in the MapInfo Discover Tutorials playlist. Subtitles are available for this.
  2. questionDrillhole Pierce Points; a powerful way to analyze and enhance your long-sections
    Released in Discover 2014, the Create Pierce Point Layer tool (within the Section Manager) converts downhole intervals into fully-attributed MapInfo Professional Point symbols. This significantly enhances the display and analytical options for this data on long- and cross-sections, such as: A ...
  3. questionHow do I display a 3D DXF file from another application (or feature database .FDB) into a Drillhole Section?
    Solution Discover 2012 introduced the powerful 3D Vector to Section tool (accessed via the Drillholes>Section Manager>Analytical tools>Display 3D Model on Section). This allows the easy display of multiple .DXF and Discover 3D .FDB vector models onto the selected cross-sections as att ...
  4. questionHow to display high-grade intercepts on drillhole sections, and create informative labels for them.
    Occurrence Are you trying create and effectively display high-grade intercepts on your cross-sections and long-sections? Here are some pro-tips. Solution 1/. Ensure you have composited your downhole assay table with the appropriate method / parameters (using Drillholes>Downhole Composit ...
  5. questionHow do I highlight different drillhole types on a section, such as Planned holes, or RAB vs RC vs DDH?
    Solution A couple of tips that may assist you with the current version of Discover (v2013). 1/. To highlight 'Planned' holes. In addition to adding the planned hole/s' collar (and survey entries if needed) information, add a single lithology entry for each planned hole to the lithology table, ...
  6. questionHow do I regenerate a section?
    Occurrence Existing drillhole cross-sections and plans may need to be updated after updates and additions to a drillhole projects collar, survey and/or downhole data tables. Examples of changes to these files that may warrant section regeneration include: - new drillholes are added to a pr ...
  7. questionDownhole data is not displaying correctly or does not appear in drillhole cross-section or plan views.
    Solution Check the following common issues: Do the downhole data tables (eg assays, lithology, structure) all have the following 3 columns with identical names; Hole_ID, Depth_From and Depth_To (or similar). These fields must be in the same position and order in every table (easiest if they ...

Solution This issue was resolved in the Discover 12.0.31 patch (build 31), which you can download from here (or vi ...
  12. questionHow do I display downhole point data such as geophysical or structural data with only a single Depth field?
    Occurrence Often down-hole data is collected as point data located with a single depth field. Examples include structural measurements such as foliation and bedding observations, geophysical readings (e.g. magnetic susceptability), or water table depth. Solution Discover's Drillhole module requi ...
  13. questionThe top portions of my drillholes are missing annotation labels and downhole data or display label overprinting at the collar.
    Occurrence When I create a drillhole cross section in Discover 10.0 or 11.0, the depth labels and tick annotation from the upper intervals of the drillhole traces are missing, and are instead all overprinted at the collar position. When I apply downhole data, the data is missing from the uppe ...
