WellCAD Basics - Advanced Logic Technology

Inserting intervals:
After selecting the statistical parameters you
can insert intervals anywhere on the borehole
document. These intervals do not require a
log to be inserted first. Drawing the intervals
is very similar to inserting litho beds or
comment log boxes. Ensure no log is
selected. Hold down the SHIFT key and
drag the mouse to insert an interval (current
depth displayed in the Status Bar), drag the
upper or lower limit of the interval with your
mouse to adjust the limits.

You can also click the Add row icon to
add a new row and enter the top and bottom limits of the interval manually.
Clicking the Add rows from… icon allows selection of a reference log. A log of
type Lithology, Comment, Strata, Interval or Core Desc can be chosen. For each
interval found in the reference log a new interval will be created in the Statistic bar.
Intervals are displayed as shaded areas on screen as long as the Statistics Bar is
displayed. (The selected parameters remain in the bar for the lifetime of the window.
But they will not be stored within the WCL file.)
For each interval one row in the list control of the Statistics Bar will be inserted. If
you want the displayed parameters being equally spread across the width of the bar,
right click on the column header and choose Show all parameters.
Depending on the input log type one or multiple columns may be created. If, for
example, the average of a Lithology Log is computed one column for each lithology
component will be created. The calculated value is the percentage of the cumulative
thickness of this component within the interval.
Export of statistical data:
Click the Export Statistics icon. An ASCII file with *.TXT extension will be
created containing all the information shown in the Statistic Bar separated by
commas.
Deleting intervals:
Hold down the CTRL key and click into an interval to remove it. You can also select
rows in the list control and click the Remove selected rows icon.
