6.2.2 Reference to a WITSML Well Data Object

Topic Version1Published12/09/2016
For StandardPRODML v2.0

Optionally, a reporting entity can reference a data object containing full data. An example of this is shown in Figure 6.2.2-1 . The XML on the left shows a reporting entity object, in this case a well. In this example, more information about the well is desired, so a link to a WITSML well, object is specified. The right side of the figure shows the referenced WITSML well object.

The kind of reporting entity being a well, linked to a Well object, is not enforced but is expected (red circle).

The link is made using the Energistics Common data object reference class (from the Energistics CTA), which is named Target Facility. The key data element is the UUID, which is the same as the well object’s own UUID (blue box).

In the worked example, these “full data” object files can be found in the sub-folders “Wells” and “wellboreCompletions”. Examples are provided for all the 5 wells and 6 wellbore completions listed in Figure 6.2.1-2 .
