Well Test Satellite

Oil Well Test are fully supported by Smart-Alek device types where the oil well test calculation is done from the server side.

In Zedi Access, the Well Test Satellite feature is accessed two ways:

1. by clicking on the test tube Well Test Satellite icon, or
2. by clicking the link in the drop-down menu on the Well Site Display.

Within Well Test Satellite, there are four tabs:

1. Test and Report
2. Meter Parameters
3. Parameter History
4. Well Manager

The Well Test Satellite function normally opens on the Test and Report tab, unless no test wells have been set up in the system, in which case, the function will open on the Well Manager tab.

Adding and Editing Test Wells

To add wells to a test site, or edit existing test wells, go to the Well Manager tab. The existing test wells are listed along the left side of the screen.

To Add a Test Well:

1. Click on the

Add Test Well button. The Add Test Well page opens.

2. Enter a name or LSD for the well in the Location Name/LSD field.

3. Enter the Location UWI in the appropriate field.

4. If desired, you may enter a comment in the Comments field.

5. Click the Save button to enter the well into the system. Clicking Cancel will exit you from the page without saving the entry.

Newly created wells are added to the links on the left side and the full list in the Well Manager and are now available for tests.

You cannot create multiple test wells with duplicate Location Name/LSD or Location UWI under the same test satellite. This rule doesn't apply across test wells in separate test satellites.

To Edit a Test Well:

1. Click the pencil.

Edit link on the well you want to edit. The Edit Well Location page open. 

1. Edit the fields necessary.
2. Click the Save button to enter the changes into the system. Clicking Cancel will exit you from the page without saving the changes.

The edits are reflected in the full list in the Well Manager.

Wells that have no tests associated with them can be deleted through the Well Manager by clicking the

Delete link.

Ways to View Well Tests

Go to the Test and Report tab. Test wells are listed along the left side of the screen. Previous tests for the entire satellite are listed in the main display.

To select a date range for the tests you'd like to view, choose a Start Date and End Date from the appropriate fields, then click the Apply button.

1. To filter tests by a particular status, select the desired status from the Status dropdown menu, then click the Apply button.

When viewing a specific well within the battery, you are given the ability to add well tests for the well through the

Add Well Test button just below the tabs at the top of the screen.

2. To export well test data into a CSV file, select the data you wish to export using the various filters described above (date range, status, or per well), then click the Export button.

3. The page displays ten records at a time. To view other test records, click on the First, Prev, Next, Last, and page number links above or below the test record listings as desired.

4. When viewing well test records, either for the entire satellite or for a specific well, you are presented with the following options, depending on the status of the well test:

• Click the View icon to view details of a test. This will present the details of the test record, the well test, the meter parameters of the test, the gas composition of the test, the EFM meter information, and the snap shot flow calculations.
• You can Accept or Reject the test or Append Comments through buttons at the bottom of the page.
• Click the Test Records link to return to the Test and Report menu without Accepting or Rejecting a test.
  You cannot view details of a Failed test.
• Click the Accept link to Accept a calculated test. A pop-up will appear allowing you to append comments if desired. Comments are optional for accepted tests. Click the Accept button in the pop-up menu to complete the process.
   
• The Accept link only appears on tests with the Rejected or Validate status.
• Click the Reject link to Reject a calculated or previously accepted test. A pop-up will appear for you to append comments to the rejection. Comments must be appended for test rejections. Click the Reject button in the pop-up menu to complete the process.
   
• The Reject link appears with tests with the Validate or Accepted status.

Running Well Tests

Well Tests are run through the Test and Report tab.

To Run a Well Test:

1. Click the Add Well Test button. The Add Well Test Record page opens.

2. Enter the start and end date and times in the appropriate fields.

Tests must be run for a minimum of 5 minutes.

3. Enter the BS&W cut in percentage in the BS&W (%) field.

The BS&W % field only appears with sites using two-phase separation. If your site is running three-phase separation, you don't need to enter a percentage, as the sensors will read the oil and water percentages

4. Enter the Solution Gas Factor in the Solution Gas Factor field if necessary.

5. Enter any comments in the Comments field if necessary.

6. Click the Save button to begin the test. Clicking Cancel will exit you from the page without running the test.

If you enter a time range for when the Smart-Alek was not attached to the well being tested, you will receive an error message stating that "The record could not be created" with information on why the selected dates fall out of range. You will then have to either correct your date range, or select Cancel to exit the testing screen.

7. The test will appear in the Test and Report screen main section with the Status of "Calculating".

To view the completed test, refresh the screen by exiting and returning to the well-specific view or by clicking the Apply button. If the system is done calculating the test, the refreshed screen will change the status of the test to either "Validate" or "Failed", depending on the success of the test.

In doubt about the actual test period?

Click Gas Flow Rate sensor on the Well Site Display for visual clues as to appropriate test times. The area circled in red indicates a change occurred. Holding your cursor on top of data points will give you the exact date and time that point occurred.

Entering Meter Parameters and Gas Composition

The meter parameters, like meter run and gas composition, for all the wells in the satellite are viewed by clicking on the Meter Parameters tab. From here, you can add and edit information on an on-going basis, based on your well permissions.
