1 Petrel TIPS&TRICKS from SCM Maps: Knowledge Worth Sharing Map Annotation A map is a graphic representation of some part of the earth. In our industry, it may represent either the surface or sub surface; structure, depth, thickness or some other property. A map contains a series of components that convey its purpose to partners or peers. It must also contain descriptive information which helps the reader interpret the information on the map. One type of this descriptive information is text. We may place text on a map to identify locations (lease names, OWC locations, etc.), legends, titles, etc. In Petrel, this may be accomplished in two ways: 1. Using Labels on the map or viewport 2. Using an Annotations File It is much simpler to use labels, although they are often limited to one map or viewport. The annotation file may be used with multiple maps or viewports. Using Labels on the map or viewport: Place individual text strings (labels) on a map by clicking on the New object in window New label : icon and choosing You then click to locate the label on the picture. The label appears on the map as <Label 1> and also under the Map Window in the Windows tab. 1

2 To change the label, bring up its Settings menu and type in what you want for text: Change the font size, whether it has a lined or filled background and whether it is Bold, Italic, etc. and click Apply. You will see it change on the picture. Under Set/pick mode, you may move the text around the map using the four pointed arrow icon. In similar manners, you may add lines (arrow) and boxes (rectangle) to the window. Again, place them with the cursor, and change the color, style, etc. in the Settings menus. The following is an example of the Line settings: 2

3 Once again, they may be moved around in Set/pick mode. These label and line annotations may also be used in Plot windows. The labels are associated with the Plot window and not with a particular viewport; but may be placed anywhere on the plot. Using an Annotations File: An Annotations file is a special file in the Input tab of Petrel. This file allows you to attach names, etc. to objects in the display. Only one Annotations file per project is allowed and may be used in combination with the Label annotations described above. To create this file, click on Insert and choose New annotations. If New annotations is grayed out, you already have an Annotations file in the project. 3

4 A new Annotations file appears at the bottom of the Input tab: Click on the Annotations Object name and bring up the Settings Window: Under the Style tab, the text styles are defined. Petrel defines three of them for you; Default, Small and Large. You may use one of these or add a new one using the Add new text style icon. 4

5 For each text style, you may change the font size, color and whether to use Bold and/or Italic, etc. In a map window, you may also describe the background color and frame view if you wish. Under the Settings tab, you define the different text strings that may be placed on any map you want to construct. This is also the location where you may associate an object with an annotation. Remember, only one Annotations object is allowed per project; so you must describe all text for all maps here. The Settings tab starts off blank: You may add as many lines to it as you wish. To add a new table item, press the Append items in table icon. A new row will be added for each time you press the button. Pressing it once will make the window appear as: 5

6 You may: Enter the object to associate with the text (Icon) Enter the text to place on the map (Text) Enter the X, Y and Z Coordinates (X Coord, Y Coord, Z Coord) Enter the Rotation Angle (Angle) Set it to be displayed only when the associated file is also being displayed (Show) Set it to always display when the Annotation File is checked (Show Always) Tell it which text style from the Style tab is to be used (Text style) 6

7 In the following example Map window: The contour lines have been turned off; only the contour fill shows the structure surface. The blue dotted line is the GOC The red dotted line is the OWC The black line is a lease boundary We wish to put the Leaseholder names only when the Lease line is visible, the label GOC only when the GOC line is visible and the label OWC only when the OWC line is visible. To do this, in the Annotations file Settings dialog Settings tab: 1. Click the Append item in table icon for the first label (the OWC). The table looks like: 7

8 2. Enter the text OWC under Text and use the Blue Arrow to enter the object name under Icon. Use an Angle of 0.00 and click the box under Show 3. Click the Apply button and put a checkmark in the box in front of both the Annotation file and the object in the Input tab. The table shows that the text will use the Default Text Style: 4. The text OWC will now appear in the Map window: 8

9 5. Use the Select/Pick mode icon and a four ended cursor appears over the text: 6. Drag it wherever you wish to place it on the map. You may rotate the text by either changing the Angle in the Annotations file Settings tab or by using the Shift key and moving the object with the cursor. After moving and/or rotating, you will see the new coordinates and angle in the Annotations file Settings tab: 7. Notice that it has added a Z Coord value from the file under Icon 8. Add text for the GOC in the same manner: 9. We now wish to add two lines of text for the Leaseholder names. Add two more lines using the Append item in the table icon. Put in the Text. We will use Lucky Oil Company and Unlucky Oil Company as the Leaseholder names. Associate the same file from the Input tab with both text strings. In this example, we will use the Large Text style for both names: 9

10 After moving both text strings, our Map window looks like: 10

11 10. We may now change the Large Text style to have a yellow background and a frame. 11. This changes our picture to: 12. If we want to have some text annotation on our picture all the time (without associating it with a file); a. Enter another line in the Settings tab. b. Type in the text c. Click the box under Show always d. Click Apply and (after moving the text to the bottom) the text appears: 11

12 13. Now, let s add a new Text style and assign the new text to the new Text style. a. Return to the Style tab and click on the Add new text style icon b. Give the new style a name of Oil Field c. Make the Font size be 16 and Bold d. Click Apply e. Back under the Settings tab, change the Text style to the one just created and click Apply: 12

13 f. You will see the text change to the new style: Remember that this one Annotations file must be used for all maps. Control what goes on each map by associating the lines with a Petrel object. Also remember that for the text to appear on the Map window, both the Annotations file and the associated Petrel object must be displayed. This is true when making a map interactively or when making a map using a Workflow. The Annotations file may be used with Map viewports in a Plot window the same as it is used in a Map window This file may also be used with 2D and 3D windows, but the text is always rotated to horizontal for the viewing angle no matter what the Annotations file calls for or what rotation the window might have. The Annotations file may NOT be used in Intersection or Well Section viewports or windows. 13
