Headers Page

The Headers page of the well test configuration control defines the list of headers included in each well test configuration. Each header corresponds to a separator facility, and this is where you define its point tag, properties, and the associated wells.

The Headers page consists of the following sections:

Screen designer tip:
You can hide this page by disabling the Show headers property in the Canvas Design view.

To configure Well Test Headers

Perform the following steps to configure the headers properties, referring to the property definitions below:

  1. Click the Headers tab on the left side of the screen.
  2. Click Add header or click on previously configured header.
  3. Configure the Enabled check box and Template to be used with this header.
  4. Click to Add well or click on previously configured well.
  5. Click to Enable the well and add the Enabled UDC.
  6. Save any changes. The status of a newly added Header is Idle.
  7. Click the Templates tab on the left side of the screen to continue well test configuration.

Headers

The Headers section of the Headers page defines the headers to be included in each well test operation.

Property Description XML

Tag

Specifies the fully qualified facility tag of the well test header facility in the format: site.service::facility_id.

tag

Add header

  • Click Add header to select a facility tag for the new header.
 

Delete header

  • Click Delete this item to delete a selected header, as necessary.
 

Properties

The Properties section of the Headers page defines the general properties of each header included in the well test operation.

Property Description XML

Tag

Specifies the fully qualified facility tag of the well test header facility in the format: site.service::facility_id.

tag

Description

Specifies the description of the well test header facility retrieved from the Facility service.

 

Enabled

Indicates whether the header is enabled. Options include True or False.

enabled

Template

Specifies the name of the header template to use for this header, which must match a defined header template name. The header template name, type, queue UDC, valve positions, and related commands are defined in the <HeaderTemplate> element. More than one header can use the same template.

template

Wells

The Wells section of the Headers page defines the wells associated with each header. Each well is associated with a facility tag, a position number, enabled value or enabled UDC, and a sequence number or sequence UDC. Only enabled wells will be tested. The configuration options in the Wells grid differs depending on the template type and the sub-header configuration on the Templates page.

Sub-headers and sub-header positions

When a header is associated with a template that has sub-headers enabled, the Wells grid will show all the available sub-header and sub-header position combinations along with any configured wells.

See Positions, Headers, and Sub-Headers for more information.

Property Description XML

Position

Specifies the position number for the well. This must line up with one of the positions in the associated header template. Values include 1, 2, 3, …, n.

position

Sequence

Specifies the sequence number for the well. Determines the order in which the wells are tested in the queue. The Wells queue will be updated using the current value of Sequence or Sequence UDC before starting the next test, so that the queue can change dynamically each time a new test for any position on the Header is started.

When using the Continuous or Schedule queue actions, the well test will follow the sequence order. The Well Test service reads the queue, completes the pending queue and then re-reads the configuration, pulling in the wells in the order of the sequence. Values include 1, 2, 3, …, n.

The Well.GetSequence() method in the CygNet.API.WellTest returns the sequence order.

Note: Read the definition for the sequenceUdc attribute for further usage notes on this attribute.

sequence

Description

Specifies the description of the well facility retrieved from the Facility service.

 

Tag

Specifies the fully qualified facility tag of the well in the format: site.service::facility_id. E.g., MYSITE.UIS::AMANDA_WL.

  • To associate a well with a sub-header and sub-header position, click the browse button in the Tag column to open the Select Facility Tag dialog box and select the appropriate well facility.

tag

Sub-header

For a template with sub-headers:

Specifies a text-based descriptor of the sub-header/header within the well test facility to which the position is connected. This description, in combination with sub-header position, should represent a unique value.

 

Sub-header position

For a template with sub-headers:

Specifies a text-based descriptor of the position on the sub-header to which the unique position identifier is connected.

 

Enabled

Specifies whether the well can be tested. While it is possible for the header queue to contain wells that are disabled, only enabled wells will be tested. When a well is read from the top of the header queue, prior to testing, the enabled attribute will be read.

  • If the well is enabled (True), the associated well command and actions will be processed
  • If the well is not enabled (False), the well will not be tested and the next well in the queue will be evaluated

Note: Make sure you read the definition for the enabledUdc attribute for further usage notes on the enabled attribute.

Options include True or False.

enabled

Enabled UDC

The Enabled UDC property (enabledUdc) allows the configuration of the Enabled (enabled) property by point. The defined UDC will be combined with the facility tag to formulate a point. The Enabled UDC Property /enabledUdc attribute takes precedence over the Enabled (enabled). Click the browse button to open the Select UDC dialog box and select an appropriate UDC.

  • If that point exists and has a valid value (either True or False), then that value is used to determine the enabled status.
  • If the point doesn’t exist or the value is invalid, then the enabled attribute value will be used. If in this case, the enabled attribute is not configured, and it will be assumed that the well is not enabled.

Note: This attribute allows manipulation of a well's enabled/disabled status external to the Canvas Well Test Status screen, and the CygNet Well Test Module.

enabledUdc

Sequence UDC

The Sequence UDC property / sequenceUdc attribute allows the adjustment of a well's Sequence (sequence) assignment by UDC to manage the order of well in the test on the fly. The Wells queue will be updated using the current value of Sequence or Sequence UDC before starting the next test, so that the queue can change dynamically each time a new test for any position on the Header is started.

Specify a Sequence number in the well test configuration or a Sequence UDC to take a value from a point value. When using the Continuous or Schedule queue actions, the test will follow the sequence order. The UDC will be combined with the facility tag to formulate a point.

Click the browse button to open the Select UDC dialog box and select the appropriate UDC, "SEQ".

  • If that point exists and has a valid value, then that value is used to determine the test sequence.
  • If the point doesn’t exist or the value is invalid, then the sequence attribute value will be used. If in this case, the sequence attribute is not configured, and it will be assumed that the well is not sequenced.
  • If both Sequence and Sequence UDC have assigned values, Sequence UDC takes precedence over Sequence.
  • The Well.GetSequence() method in the CygNet.API.WellTest returns the sequence order.

Note: This attribute allows manipulation of a well's sequence external to the Canvas Well Test Status screen, and the CygNet Well Test Module.

Add well

For a template without sub-headers:

  • Click Add well to select a facility tag for the new well in this header.
