UdcConfiguration, UdcDef

The <UdcConfiguration> element of the XML configuration contains elements that define the UDC definitions where the CygNet Well Test module will post well test values to well-known points. The UDCs for these points are configurable with the <UdcConfiguration> and <UdcDef> elements.

To learn about how these elements relate to other elements in a well test configuration XML structure, see Well Test Hierarchy.

Example

<WellTestConfiguration>

<UdcConfiguration>

<UdcDef name="WellInTest" udc="WTNAME" udc_desc="Well in Test" />

<UdcDef name="TimeInTestActual" udc="TMWTACT" udc_desc="Test Time Actual" />

<UdcDef name="Command" udc="WTCMD" udc_desc="Well Test Command" />

<UdcDef name="Action" udc="WTCMDACT" udc_desc="Well Test Command Action" />

<UdcDef name="Queue" udc="QUEUE" udc_desc="Well Test Header Queue" />

<UdcDef name="Result" udc="WELLTEST" udc_desc="Well Test Record" />

</UdcConfiguration>

</WellTestConfiguration>

Attribute Required Description

name

Yes

Specifies the nice name for the UDC. Possible UDC name types include:

  • WellInTest — the well currently being tested. This UDC only applies to headers in "Host" mode. UDC is WTNAME.
  • TimeInTestActual — the amount of time the well has been in this state. For example, if the well test sequence is purging, it measures how long it’s been purging. This value will get updated periodically based on the sleep timer. UDC is TMWTACT.
  • Command — the command currently being processed. This only applies to headers in Host mode. UDC is WTCMD.
  • Action — the action currently being processed. This only applies to headers in Host mode. UDC is WTCMDACT.
  • Queue — the default header queue point. The UDC is QUEUE.
  • PendingWellQueue — the configuration XML of the pending well test queue (stored as separate points' VHS blobs). The UDC is PWELLQCFG.
  • ActiveWell — the configuration XML of the active well (stored as separate points' VHS blobs). The UDC is ACTWELLCFG.
  • Result — the default point where well test results are saved. This can be overridden by the UDC in the Script action type. The UDC is WELLTEST.
  • ContinuousMode — indicates that the header is in continuous mode, that is running in a continuous loop. Configured on the General page of the Well Test configuration. Optional. The UDC is WTCONT.

udc

Yes

Specifies the UDC of each UDC type.

When you create a new configuration in the Canvas Well Test Configuration control several default UDCs will be provided. These default UDCs correspond to the UDCs used in the sample Canvas screens. You can choose to keep the same UDCs or specify others as necessary. The default UDCS are as follows:
