Creating and Editing a Line/Symbol Cross Section

To create a line/symbol cross section, click the Cross Section | Create/Add | Create Cross Section command. The program will step you through the process of importing data and selecting the wells to display in the cross section.

Creating a Line/Symbol Cross Section

To create a cross section in Strater:

Click the Cross Section | Create/Add | Create Cross Section command.
Select the collars table:
1. If a single collars table exists, it is automatically selected.
2. If multiple collars tables exist, select the appropriate collars table in the Look for Well Locations dialog and click OK.
3. If no collars table exists, select the file that contains the collars information in the Open Collars File dialog and click Open. For example, select Example Data.xls from the Samples folder and click Open.
  1. In the XLS Import Options dialog, select the Collars sheet and click OK.
  2. In the Specify Worksheet Column Definitions dialog, make sure that Specify Column Header Row is checked and that the row number is set to 1. Click Next.
  3. In the Specify Data Type and Column Positions dialog, make sure that all columns are listed correctly. Click Finish.
At this point, a map view is created with the wells in the collars table. In the Create Well Selector dialog,
1. Set the order the wells are displayed in the list on the right side of the dialog. The first well listed is on the far left side of the cross section. The last well listed is on the far right side of the cross section. Wells are displayed in the cross section in the order listed on the right side of the dialog. To rearrange the order, click on a well on the right side of the dialog and drag it to the desired location in the list.
2. To add wells to the cross section, click on the well name on the left side of the dialog in the Available wells list. Click the Add button to add the well to the right side of the dialog.
3. To remove wells from the cross section, click on the well name on the right side of the dialog in the Wells in selector list. Click Remove to remove the selected well.
4. When all the wells are in the proper order, click OK. The wells should be listed as DH-1 first and then DH-2 for this example. After clicking OK, the well selector line is created in the map view.
In the Import Cross Section Data dialog,

Set the Cross section log type to Line/Symbol log.
Click the Import Data button for DH-1.
In the Import Data dialog, select the Example Data.xls file and click Open.
In the Multi-Sheet Selection dialog, select the Depth sheet and click OK.
In the Specify Worksheet Column Definitions dialog, make sure that Specify Column Header Row is checked and that the row number is set to 1. Click Next.
In the Specify Data Type and Column Positions dialog, make sure that all columns are listed correctly. Click Finish.
Since both logs now have a Table and Data Column defined, click OK.
Click OK.

In the Import Layer Marks dialog,
1. Check the Specify layer data check box if you wish to include layer marks from the layer marks table or tables.
2. Set the Table for each Hole ID to the layer marks table. Layer marks tables are depth tables containing depths for the tops (or bottoms) of layers.
3. Set the Data Column for each Hole ID to the layer column in the layer marks table.
4. Click OK.

The default cross section is created. Because the cross section was created from Line/Symbol log, the logs are displayed showing only the line/symbol logs and no layers are created. If Lithology/Zone bar log had been selected in step 4a, the logs would be displayed showing the wells that were selected and the connected layers between the wells in the cross section would also be displayed.

Connecting Wells

With line/symbol log cross sections, wells are manually connected by using layer marks. Layer marks can be created in another program, such as Excel and imported into the cross section. Or layer marks can be selected directly on the line/symbol logs displayed on the cross section. To manually click each layer mark:

Click on the Cross Section object in the Object Manager.
Click the Cross Section | Layer Marks | Create/Edit command to start picking locations on each log where a layer should be located. The cursor changes to .
Click on either log in any locations to make a layer mark. Generally, the top or bottom of the layers should be clicked to create a data file of tops. As the mouse hovers over a log, the log name and depth appear in a large box beside the log. This makes it easier to select the precise location of each layer mark.
After clicking on the log, the Name The Layer dialog appears. Type a name for the location where you clicked, such as Layer 1, or the actual name of the layer. Click OK in the dialog after naming the location.
Continue clicking on each log in the cross section to assign the layer top or bottom locations. Not all layers need to be assigned for each well, but in order for the wells to be connected some of the same layer names should be assigned to each log in the cross section.
If the area from the top of the well to the first layer should be filled, be sure to click on the top of each well and assign a layer name, such as Top, Overburden, or KB.
If the area below the last layer should be filled, be sure to click on the bottom of each well and assign a layer name, such as End.
If a location is selected incorrectly, right-click on the same location to remove the layer mark.

After clicking a few layer marks on each log, your

cross section may look something like this.

After selecting all layer marks, press ENTER on the keyboard to end layer mark creation/editing mode.
In the Save Layer Marks To Table dialog, check the Save layer marks to table option to save the marks to a table. You can select any of the existing tables, or type a new table name next to Table name. Click OK and the layer marks are saved to the table.
Click Yes in the warning message which indicates that the cross section will be redrawn. The layer marks are now connected across the logs.

The layer marks are now connected across the logs. Layer labels have

been added by checking the Show Layer Labels option in the Property Manager.

Notice that the Potential zone layer mark on DH-1 does not have a layer. This is because the same mark does not exist on DH-2. A new layer can be created named Potential zone. With the Cross Section object selected, click the Cross Section | Create/Add | Connect Logs with Layers command.
In the Select Or Enter Layer Name dialog, click on the existing name and select Potential zone from the list. Click OK.
Click on the DH-1 log near where the Potential zone layer mark was created.
Hold down the SHIFT key and click on locations between the two logs to make a pinchout layer.
Click on the DH-1 log above the Basement layer line.
Press ENTER on the keyboard or double click the last point to end the layer creation mode. A Potential zone layer is created and automatically filled.
To fill the rest of the layers, make sure that the Layers object is selected in the Object Manager. In the Property Manager, click on the Layers tab and check the box next to Fill between Layer Lines.
Since the Potential zone layer was created before filling the layers, it is now at the bottom of the list of layers in the Object Manager. Click on the Potential zone layer and click Arrange | Move | To Front.
To change the colors of the layers, the scheme can be edited. Click the Home | Display | Scheme Editor command.
Open the Cross Section Scheme by clicking on the next to Cross Section Scheme.
Click on the first item in the scheme. Assign fill colors and properties.
Repeat steps 19 and 20 for each additional item in the scheme. When the scheme colors are set appropriately, click OK to close the Scheme Editor.
When all edits have been made, the layer lines can be unchecked in the Object Manager. This leaves only a single label in the center of each layer. The cross section may look like the following.

After editing the layer colors and label properties, the final cross section may look like this.
