Drillhole data forms the basis for creating models in Leapfrog Geo. Because drillhole data often contains errors that reduce the reliability of a model, Leapfrog Geo has tools that help you to identify and correct errors in the data and work with the data.
In Leapfrog Geo, drillhole data defines the physical 3D shape of drillholes. It is made up of:
- A collar table, containing information on the location of the drillhole.
- A survey table, containing information that describes the deviation of each drillhole.
- At least one interval table, containing information on measurements such as lithology, date or any numeric or textual values. An interval table must also include collar IDs that correspond to those in the collar table and sample start and end depth.
If you have the Hydrogeology module, a screens table can also be imported.
When a project is first created, the only options available via the Drillhole Data folder are for importing data. See Importing Drillhole Data for more information on these options.
Once data has been added to the project, a Drillholes object will be created that serves as a container for the tables imported:
When there are errors in the data, the relevant table will be marked with a red X (). See Correcting Data Errors for more information on fixing drillhole data errors.
Leapfrog Geo also has tools for creating new lithology data columns from existing columns in order to solve problems with the drillhole data. See Processing Drillhole Data for more information.
You can open each table by double-clicking on the table (). The table will be displayed and you can make changes. See The Table Dialog.
With Leapfrog Geo, you can also plan drillholes and evaluate them against any model in the project. See Planning Drillholes for more information.
