Apply to Commingle Production
As outlined in Section 52 of The Oil and Gas Conservation Regulations, 2012, an operator must apply for and receive approval from the Energy Regulation Division (ERD) of the Ministry of Energy and Resources to commingle production before recompleting a well, unless otherwise approved by a Minister's Order.
Oil or Gas Wells
Commingling oil/gas applications will be handled as either routine or non-routine in Integrated Resource Information System (IRIS), depending on answers to declaration questions provided by the applicant. If it is routine, an IRIS authorization is granted automatically by ERD immediately after the applicant submits the application. If it is non-routine, the application is identified as requiring further review by ERD prior to being approved or denied.
Water Source Wells
Application to commingle water source wells must be submitted through IRIS using the Commingling Disposal/Others application type. All the applications will be reviewed by ERD before being approved or denied.
Need information on how to apply for commingled disposal wells? Visit the Disposal/Injection Wells page.
An applicant must have an Integrated Resource Information System (IRIS) account and the appropriate permissions assigned by their IRIS Security Administrator to submit a commingling application.
To be eligible for a routine authorization for oil or gas production well, an operator must meet the following requirements:
- A stabilized production rate of at least six months is established in one of the pools to be commingled;
- The lessor(s) and lessee(s) in all pools are identical;
- One of the pools to be commingled is producing at such a marginal rate that segregating production or drilling a twin well can't be justified;
- The pools have compatible producing characteristics and reservoir properties, such as similar Sandface pressures;
- The pools are in close proximity in terms of producing depth;
- Oil or gas pools to be commingled don't contain significant underlying water identified in logs or through production;
- Oil pools to be commingled do not contain gas zones identified in logs or through production; and
- There is no enhanced oil recovery project in the immediate area, including waterflood.
If one or more of the above requirements are not met, the operator may still apply. However, the application may be handled as non-routine.
3. How To Apply
Oil or Gas Wells
To apply for a commingling application, log in to IRIS and complete the Commingling Oil/ Gas application process.
For further guidance on how to apply, please refer to the Guideline PNG038: Application to Commingle Production.
Water Source Wells
To apply for water source wells:
- Complete the Application to Commingle Production Form. See the Form Instructions tab of the application for details on how to fill the form.
- Complete the Reclassification/Recompletion Form (part of reservoir), if required. For more information, see Guideline PNG024: Reclassification and Recompletion.
- Confirm that all the information is complete and accurate, and forms are dated and signed.
- Log in to IRIS and complete the Commingling Disposal/Others application process for authorization and attach the required documents.
5. Further Information
Upon approval, pending status for a commingled completion is available for immediate reporting in IRIS. The applicant has one year to report on the completion or the authorization expires. If it expires, the well is no longer authorized to commingle, and a new application is required.
