Adding and editing log annotations

You can add and/or edit log annotations for any log and display them in the Well View. Log annotations are added to a specific well, at a given depth and value for the log, but you can change this manually. In addition, log annotations can be customized by changing the font and font color, background color, border color and thickness using the options available under the Display Settings tab.

Annotations are added to a log that is displayed in the Well View by selecting the Annotations > Add... option from the context menu of the log or the track. This will open the Add Annotation form, which allows you to type in the text for the annotation and specify the formatting. By default, annotations are represented in the Well View track as an anchor, a small triangle symbol, which is added to the log at the point which was right-clicked to open the log context menu. This point is displayed as a red dot. The anchor position can be changed using the settings available under the Position Tab.

When you switch between views, the same annotation created for the same log is automatically displayed/updated regardless of which view triggers the add/edit form.

    3. Wellbore  A read-only field that displays the wellbore that the log annotation will be attached to.

    Log  The specific log which the annotation will be attached to is selected in this drop-down list. Only those logs that are displayed in the particular track are available for selection. If only one log is displayed in the track, it is selected by default.
