In the first line of the dialog enter the value you would like to replace. The second
line should contain the new value. The example shown in the dialog box above
replaces the lithology code 1288 by the string Sst. Use the Replace or Replace All
button to alter only the current or all data values. If the Match entire cell contents option
is not checked the “Find” algorithm will look for the specified part of the data value
only and will only replace this part of the value. E.g. finding Sand and replacing it by
S will find the value SandStone. After replacing it the new value will be Sstone.
Most logs can be converted to other log types in order to use different presentation
styles and data format. E.g. a Mud Log can be converted into a Well Log in order to
perform calculations with the formula parser or a Lithology Log can be converted
into a Comment Log to get a quick lithology description column in text format.
� Select the log you want to convert.
� Open the Edit > Convert Log To menu.
� Click the log type you want to convert to (not possible conversions are grayed).
The conversion options for each log type are explained in Appendix A.
Since WellCAD version 4.2 an optional Undo functionality is supported. As the
Undo functionality may slow down the workflow when dealing with large data
volumes (i.e. a memory copy needs to be made for each Undo step) the Undo can
be switched on or off. This can be done on the Undo tab in the Tools > Options
dialog.
