Percent cuttings data are collected normally during mud-logging and are used to denote the relative percentage of different lithologies at a depth. For example, the relative percentages of sand, shale, and silt may be entered at several depth intervals. The lithologies that can be entered for the percent cuttings are specified in the percent cuttings column of the template. The symbols for each of the lithologies will be scaled and drawn at each of the depth intervals.
To add or edit the percent cuttings data select the Percent Cuttings menu item from the Edit menu or click the left mouse button inside the Percent Cuttings column. The Log Percent Cuttings form will be displayed.
On this form you can enter the Start and End Depths of the cuttings interval and the percentage of each lithology type that shows up in the borehole cuttings.
E.g 50% Sand
25% Silt
25% Shale
The total percentage of all lithologies must be less than or equal to 100%.
