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.

 

There are several ways to edit percent cuttings data, either:

 

•click on the percent cuttings column on the log

•double click on the percent cuttings object on the sidebar

•select Edit > Percent Cuttings

•or select Popup > Percent Cuttings

 

After this the Percent Cuttings form will be displayed. At the bottom of this form there are buttons to move to the first, previous, next, and last interval or to add and delete intervals.

 

(The appearance of the form will differ slightly depending on if it is WinLoG or WinLoG RT)

 

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.The total percentage of all lithologies must be less than or equal to 100%.
