Usually the Main Settings dialog box of the new log is displayed next
To see the numerical data contained in a log the Tabular Editor providing a
spreadsheet of the actual data set can be called up. Additionally the user can also
observe the data values of a selected log in the Status Bar of the borehole window
while moving the mouse over the data set.
1.3.1 Log Types and Their Characteristics
An overview of all log types contained in WellCAD, their main purpose, data format
and display styles, is given hereafter. A more extensive description of log types
including their display settings is given in Appendix A.
The following list provides for each log type:
- A short description of the log’s characteristics and purpose of use.
- The format of the data container. This format corresponds also to the ASCII
file import /export format.
- An overview of the main data presentation styles of the log.
1.3.1.1 Well / Formula Log
Description:
Single point data sampled at a constant rate. The Well Log is used to display any
kind of equally sampled geophysical data as curve (e.g. Gamma Ray, Density,
Resistivity, Porosity, Transit Time). Well Log data is generally imported from LAS,
LIS, DLIS or ASCII files (*.txt, *.csv) but can also be generated interactively (e.g.
grain size curve in core description). Formula Logs are calculated curves using one
or more Well Logs as data source. They are dynamically linked to Well Logs.
