Sample Well Test Screens and Scripts

There are sample well test screens and scripts included on the CygNet CD_Image. The .can files must be opened in the Canvas HMI application, are based on a sample configuration, and must be modified to work within your installation.

Sample Files Location

In the CD_Image folder find the Samples\Well Test folder, which contains the following files:

• Scripts\GetHistoricalWellTestData_Sample.vbs
• Scripts\ProcessCalculationsGeneric.vbs
• several .svg images used on the Canvas screens
• Well Test Configuration.can
• Well Test Status.can
• Well Test Detail.can

Some things to consider:

The Canvas screens are configured with C4PROD.BSSCAN as the BSS source. You can change the site service by using the Find/Replace feature in Canvas. See the instructions below.

The Well Test Status.can Canvas screen uses the well test configuration XML. The path to the point that contains the configuration is located in the script section of the screen near the top. You will need to modify this according to your installation. See the instructions below.

Edit the Sample Canvas Screens

The sample Canvas screens provided use hard-coded UDCs that may not be the same as the UDCs that you are using in your installation. If that is the case, then you will need to change the configuration of the various objects to match your installation. To use the screens, perform the following steps.

1. Copy the files to your BSS under any folder you wish, e.g. WELLTEST.
2. Change file properties from read-only to writable, if necessary.
3. Open Canvas and navigate to the Backstage menu and select the Find/Replace option.
4. Type "C4PROD.BSS\WELLTEST" in to the Find box.
5. Type "MYSITE.SERVICE\FOLDERNAME" into the Replace box, replacing MYSITE with your site's name.
6. Perform another Find/Replace action and replace "C4PROD.BSS" with "MYSITE.SERVICE"
7. Use the Manage button to select all the files from the BSS folder where you copied the files to. Click OK.
8. Click the Replace button.
9. Open the Well Test Status.can screen. Switch to the Script view.
10. This screen references a PNT point where the well test configuration XML is stored. In the Script section of the screen, there is line of script that says:

string point = @"C4PROD.UIS:WELLTEST_CONFIG_V3";

Change the value of 'point' to be the fully qualified point value where the configuration resides in your installation.

11. Return to the Design view and run the screen.

Well Test Configuration

The Well Test Configuration sample screen (Well Test Configuration.can) is a Canvas screen that can be used to easily load, configure, and save the XML required by the CygNet Well Test Module using a friendly user interface. The sample screen contains several Canvas controls, including a Text tool, Edit Box, Combo Box, Buttons, and a Well Test Control.

The Well Test Control (CygNet.API.WellTest.Controls.dll) is a plugin control assembly that is available for use in Canvas to allow the manual definition of the well test configuration XML file. This plugin provides a user-friendly method for defining the necessary elements required to execute a well test via a Canvas screen. Using the control assembly and a configuration screen you can easily define the following well test properties: point scheme, data retention value, relative facilities, UDCs, headers, wells in the well test, header templates, positions, commands, and associated actions for each command.

See Configuring Well Test Using Canvas for more information about using this screen.

Well Test Status Screen

The Well Test Status sample screen (Well Test Status.can) is a Canvas screen that reads the well test configuration XML file and presents a grid of test facilities with some status information. The lower half of the screen is driven by the test facility selection in the grid. Along the left side of the screen are three process variables showing various rates for the current well in test.

The grid on the far right of the screen (Wells) is a list of associated wells for the selected header. The test queue can be altered using the Add, All, and Next buttons, as follows:

• Add — adds the selected well to the bottom of the queue
• All — adds all wells to the bottom of the queue
• Next — adds the selected well to the top of the queue
• Details — click to open the Well Test Details screen, below

The grid in the middle of the screen (Queue) represents the current queue. The buttons below that grid control the actions of the queue:

• Start — starts processing the wells in the queue
• Stop — stops the entire well test operation
• Abort — aborts the current well in test and proceeds to the next well in the queue
• Complete — exits out of the current test state of the well and proceeds to the next action in the sequence. For example, stops the waiting and process the well test record.
• Refresh — refreshes the queue. The screen is refreshing the queue every second.
• Clear — clears the queue. This doesn’t stop the current well in test.

There is a Details button below the associated well grid. Click the Details button to open the Well Test Details screen.

Well Test Detail Screen

The Well Test Detail screen (Well Test Detail .can) is a Canvas screen that shows further detail about the selected well from the associated well grid.

The upper portion of the screen shows test time UDCs for the selected well: the Actual Time in Test, Target Test Time, Minimum Test Time, and Purge Time, provided they are configured. The Actual Test Time and Target Test Time are included on the chart.

The lower portion of the screen shows the raw Well Test Records for the selected well. The Days Back edit box and Refresh button can be used to adjust starting day of test records.
