Text Interval columns are similar to Remark columns in that they can be used to display text at any depth. In Text Interval columns a top and bottom depth for the text is specified. An optional line can be drawn across the column at these top and bottom depths.
Text Interval columns can also be linked together so that the top and bottom depths only need to be specified once for all of the linked columns. This is useful for samples and laboratory results that are shown on several columns. Facies, Constituent, and Member columns can also be linked. The template for the borehole log specifies which columns are linked.
Text Interval columns can be entered and edited by selecting the Text Interval submenu of the Edit menu and then selecting the name of the column or by clicking the left mouse button inside the column on the borehole log. After performing one of the above tasks, either the Text Intervals form or the Linked Text Intervals form will be displayed.
