Lithology Keyword Scheme

Lithology keyword schemes link words or numbers in a table column with contact line, fill, line, and font properties. Each item in a keyword scheme has different properties that are displayed in lithology logs in borehole views and cross section views. Lithology keyword schemes can define rock type, alteration, layer information, etc.

Data Requirements

Lithology keyword schemes require a column of text or numbers. Note that lithology keywords are case-sensitive.

Reusing a Lithology Keyword Scheme

A lithology keyword scheme can be used with multiple data tables in multiple projects. When selecting a data table and data column, be sure that the data column contents match the lithology keyword scheme's item names.

To use an existing lithology keyword scheme, click on the lithology log. The properties are displayed in the Property Manager. Set the Lithology Keyword Column and Lithology Scheme to the appropriate column and scheme.

Converting a Lithology Keyword Scheme to a Keyword Scheme

Click the button to convert a lithology keyword scheme to a keyword scheme. This button is only available when a lithology keyword or keyword scheme is selected. Highlight the scheme to convert and click the button. This is useful if you wish to reuse schemes for different log types without the necessity of recreating complex schemes.

For example, if you created a lithology log, a lithology keyword scheme is created. You can design the lithology keyword scheme exactly how you want it to appear. To use the same scheme item names and properties with a zone bar log,

Click on the keyword scheme to select it.
Click the button to copy the lithology keyword scheme. A duplicate lithology keyword scheme is created.
With the duplicate scheme selected, click the button.
The duplicate scheme is converted to a lithology keyword scheme and moved under the Lithology Keyword scheme type list. The lithology keyword scheme is created with the same properties as the keyword scheme.

If the button is not available, a keyword or lithology keyword scheme is not selected. Click on the appropriate keyword or lithology keyword scheme name to convert the scheme.
