Miscellaneous 2D Striplog Options

Menu Options

Zero-Thickness I-Data & T-Data Intervals: Use this setting to define what should happen to I-data and T-Data intervals that have no thickness (i.e. Top-Depth = Bottom-Depth), such as results returned from labs with a single depth only.

This option is available by clicking the Miscellaneous Options button at the bottom of the RockWorks 2D Striplog Designer window.
- Omit: Choose this option to discard zero-thickness I-data and T-data.
- Expand: Choose this option to display zero-thickness I-Data and/or T-Data intervals.
  - Thickness: Enter the thickness that zero-thickness data should be changed to. The program will center the interval at the original depth (i.e. the top of the interval is equal to the original top minus half of the new thickness height).

Unwind (Single Log Only): This option is used to plot a profile of a deviated borehole in which the azimuth is constant and normal to the viewer. Note that this is not a "projected" profile (ala' the non-unwound striplogs or the projected profiles).
- The following example illustrates the differences. Consider the borehole depicted in 3D within Figure 1. A projection into a vertical plane that is oriented N0E results in the diagram shown within Figure 2. Notice how the Figure 2 diagram becomes garbled where the log projects over itself. There is simply no way to produce a projected section that does not have this problem (at least with this extreme example). Conversely, the diagram depicted within Figure 3 shows how the new "unwind" option can be used to show the entire log without any overlap.
- Note: The unwinding process always deviates the log (varies the inclination) to the right of the borehole collar.
View Direction (Single Log Only): This setting applies only to single, non-vertical 2D logs. Here you can choose the direction toward which the log is viewed. For example, to view the log from the south, toward the north, you would enter 0.0, or to view the log toward the east, you would enter 90. This will be ignored for Unwound logs, above.
