We are testing a new feature in Surfer Beta, where you can apply color to the intervals in your 3D drillholes using a text keyword. This makes it easy to visualize stratigraphy, mineralization content, alteration zones, formations, etc in your 3D drillholes.
Simply include the text keyword in your interval table for your drillhole data, and load it along with the other drillhole data. For interval (from/to) data, you can choose to apply colors to either intervals (numeric data) or keywords (text data). Apply any color to the individual keywords, create a legend of the keywords, rearrange the order in any way that you want, and even rename the keywords if you want the legend to show something other text (e.g. SST => Sandstone).
Display colors based on keywords (e.g. lithology) in 3D drillholes and create a legend with the corresponding names
Making sure our development meets your needs is important to us at Golden Software, so we would like to ask your feedback on this feature.
What is this new feature
This feature gives you the option to apply colors to specific text keywords for your drillhole intervals. This allows you to:
-
Show lithology, stratigraphy, mineralization or alteration content, or other information with depth
-
Display formation names or age of the geology with depth
-
Visually correlate the geology between drillholes
How to use it
To use this feature, all you need to start with is drillhole data, including a collars table and an interval table. This could be saved in any data file format, such as an Excel *.XLSX file. At the minimum, the collars table must have the Hole ID, X and Y coordinates, and the interval table must have the Hole ID, From depth, To depth, and the text keyword. For example, please see the attached file at the bottom of this article: Lithology.xlsx
Then, follow these steps:
-
In the 2D plot view, click Home | Specialty | Drillhole.
-
In the Drillhole Data Import, click Browse to the right of Collars, select your data file with the collars data and click Open. If you selected an Excel workbook, select the collars data sheet to import and click OK.
- Click Add to the right of Intervals/Points, select your data file with the interval data and click Open. If you selected an Excel workbook, select the interval data sheet to import and click OK.
- Click Next.
- Select the collars table input fields and click Next.
- Select Interval (From/To) Data at the top, click Add All Fields (center right) and click Finish. The drillhole map is created.
- Note: it is helpful to select the map and click Map Tools | Map Tools | Set Limits and extend the limits slightly so that the drillholes are fully contained within the map limits and not on the edges.
- Right click over the map and click 3D View.
- In the 3D View, tilt the map up so you can view it from the side, and select the Drillhole layer from the Contents window.
- In the Properties window, click the Keywords tab and check the box to Show keywords.
- Increase the Size from 1.0 to 10.0.
- Click Edit Symbology. In the 3D Drillhole Keywords dialog, you can change the color associated with each keyword, you can change the Name of the keyword (the Name is what is displayed in the legend), and you can even drag and drop keywords to change their display order. Click OK when you are finished making changes.
- To create the legend, click Color Scales in the Contents window, and check the box in the Properties window next to Drillhole Keywords | Drillhole.
- Select Color Scales | Drillhole Keywords in the Contents window to update the legend properties, such as the location, the sample height/width, sample spacing, and the font properties.
- Make any final touches you want, such as changing the vertical exaggeration or background color under the Environment, or updating the axis properties, such as the color, titles, or adding grid lines.
