RockWorks | Borehole Operations | Striplogs | Datasheet -> Borehole Survey
This program is used to read depths, bearings, and inclinations from the RockWorks datasheet, and compute XYZ coordinates at user-specified intervals down the borehole that are recorded in a new datasheet. It also offers 2D and 3D diagram views of the deviated borehole.
Feature Level: RockWorks Basic and higher
Menu Options
Step-by-Step Summary
- Data Columns:
- Depth: Select the column in the current datasheet where the depth measurements are listed. Be sure you have your units defined.
- Bearing: Select the column in the input file where the survey bearings (in 0 - 360 degree azimuth) are listed.
- Inclination: Select the column in the input file where the inclinations of the drillhole are listed.
- Collar & TD
- Collar Location:
- X (Easting), Y (Northing), Z (Elevation): Type in the X, Y, and elevation at the top of the hole.
! It’s important that the X and Y location coordinates and the elevations are recorded in the same units, such as meters or feet, and that they match the depth units listed in the input file.

- Inclination: Select the format of the inclination measurements you have entered. Choose from:
- Up = 90 Degrees, Horizontal = 0 Degrees, Down = -90 Degrees

- Perimeter
- Annotation Size: This determines the size of the text labels along the border, as a percent of the project size. Default = 2
- Horizontal Annotation Intervals: Choose Automatic or Manual. For the latter you can specify the number of map units at which tick marks and labels are to be plotted along the horizontal axes of the profiles.

- Access the RockWorks Datasheet program tab.
- Create a new datasheet and enter or import your downhole survey data into the datasheet.
Or, open one of the sample files and replace that data with your own.
! Click the Example button to the left to load a sample file that is installed with the program.
- Select the Borehole Operations | Datasheet - Borehole Survey menu option.
- Enter the requested menu items, described above.
- Click the Continue button on the left side of the window to continue.
The program will read the well location and downhole survey information from the database. It will determine the downhole trace of the drill hole, and will calculate the X, Y, and elevation coordinates at the specified interval down the hole. If requested, it will list these computations in an XYZ List report. If requested, the 2D plan map and/or vertical profiles will be generated and displayed in RockPlot2D tab(s) in the window. If requested, the 3D diagram will be displayed in a RockPlot3D tab.
- You can adjust any of the settings in the main Options tab to the left and click the Continue button again to regenerate the data or diagrams.
- View / manipulate / save the report and/or diagrams.
TIP: The accuracy of the calculations is dependent upon the resolution settings defined in the Settings | Preferences window. See the discussion of Computational Resolution in that topic.
