CWIS Work Group
Support the business case for the CWIS Standard by showing how to capture production data for a single completion in multiple wellbores.
All data for a wellbore completion are captured according to depth interval and time interval within a wellbore. Production is reported on the Well Reporting ID.
Primary: Alberta Energy Regulator (AER), well operator
Secondary: data vendor, data analyst
Question about how to use the CWIS identifiers for multileg completion data. This shows the advantage of the Well Reporting ID.
Primary or Typical Scenario
A well (Figure 1) was drilled with three horizontal wellbores in the Viking SS and completed for a single stream of gas production.
The actual sequence of activity was:
Using the existing UWI system for well identification, three UWIs are assigned. The production is reported only on the first UWI. The other two have status of DRAIN.
This Use Case assumes that the regulator has adopted the CWIS System. It also assumes some details of the processes used by AER and Petrinex although reality might be different. The identifiers would be assigned as follows:
The following standards and regulatory procedures are assumed for the scenario:
This is based on a real example with data from the operator. Licence 0xxx263.
