Import GDS Files into the Borehole Manager
Borehole Manager | File | Import | GDS

This program is used to import Geological Data Services (GDS) format files into the borehole database. It will translate the well coordinates to the current project coordinate system. There are three supported file formats:

This data is not supplied with the RockWorks program; you must contact a GDS vendor for purchasing details.

Borehole Options Tab

Location Fields Tab

  1. Access the Borehole Manager program tab.
  2. Open the project folder (if necessary) in which the well records are to be created.
  3. Choose the File | Import | GDS option that matches the file type you're importing.
  4. Enter the requested menu options, described above.
  5. Click OK to continue.

    The program will create a separate borehole record for each well number, based on the overwrite options you specified. The program will import the well location data based on the mappings you established.

    Stratigraphic top depths, and formation names, will be recorded to the Stratigraphy data table.

    The formation names listed in the import file will be written to the database's Stratigraphy Types Table.

    In the GDSII format the deleted record (DEL), thickness (THK), coal thickness (COL), repeated tops and fault records are ignored. The information in these records do not exist in the flat file format.

  6. Post import:
    1. Stratigraphy Types: You will be prompted to review the Stratigraphy Types - it's a good idea to do so. The importer will record the listed formation names into the Type Table, and will do its best to list them in proper order (if available, the higher numbers are more recent strata and should be at the top of the Type Table) but you'll need to review their order and assign desired patterns and colors. The easiest way to define stratigraphic order here is by editing the Order column (1, 2, 3, 4, etc.) - this is the column upon which the Table is sorted.
      • If you are importing an GDS file into an existing RockWorks project, the import program will append new stratigraphy types onto the end of the existing Stratigraphy Type Table. It will not add obvious duplicates, but take care to review the Table before modeling to order the units properly and delete duplicates.
    2. Well locations: Check that the Collar Coordinates - Easting and Northing - were computed for all of the wells during import, from either the lon/lat or PLSS coordinates as you selected above.
    3. Elevations and TD: Be sure these required fields are present for all wells before you start mapping/modeling.
    4. Output Dimensions: Once all of the Location data is entered for all of the wells, be sure to establish your output dimensions prior to mapping/modeling.
  7. Once these have been entered, you can use the Stratigraphy menu tools to model and display the formation tops and bases as maps, 3D surfaces & models, profiles, sections, and fences. You can also visualize the source data on 2D and 3D logs using the Striplogs menu tools.
