Creating a Lithology/Zone Bar Cross Section

To create a 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 Cross Section

This example will use the Example Data.xlsx sample file to demonstrate creating a cross section in Strater:

  1. Click the Cross Section | Create/Add | Create Cross Section command.

  2. 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.

  3. 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.

  4. In the Import Cross Section Data dialog,

    1. Set the Cross section log type to Lithology/Zone bar log.

    2. Click the Import Data button for DH-1.

    3. In the Import Data dialog, select the Example Data.xls file and click Open.

    4. In the Multi-Sheet Selection dialog, select the Lithology sheet and click OK.

    5. 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.

    6. In the Specify Data Type and Column Positions dialog, make sure that all columns are listed correctly. Click Finish.

    7. Since both logs now have a Table and Data Column defined, click OK.

The default cross section is created. Because the cross section was created from Lithology/Zone bar log, the logs are displayed showing the wells that were selected and the connected layers between the wells are also displayed. If Line/Symbol log had been selected in step 4a for the Cross section log type, the cross section would only display the line/symbol logs.

 

Map and Well Selector Line Notes

If a well selector line already has been created and is selected, the cross section automatically uses that well selector line when creating the cross section. Cross sections are automatically created connecting all the wells in the well selector line. Wells are connected in the cross section from left to right in the order they are connected in the well selector line.

 

Connecting Wells

Refer to the Connect Logs with Layers, and layer marks Import and Create/Edit pages for information on connecting wells or changing connections between wells.

 

Data Table Requirements

Strater requires that a lithology or interval table for lithology/zone bar log cross sections or a depth, interval, or lithology table for a line/symbol log cross section.
