As part of the AER’s ongoing application effectiveness review, the AER has identified the need for an application process for short-term gas injection in the Electronic Application Submission (EAS) System. The Gas Injection – Short Term application type is applicable to operators proposing to inject produced gas back into the same defined producing pool during surface facilities turnaround maintenance and other routine outages.
The AER will assign the application to a subject matter expert for initial review. They will review and assess the following information. If the items listed below are not included in the application, the application will be returned to the applicant.
a. The applicant has identified the target formation for the short-term gas injection. This must be an AER defined pool. There are no subsurface requirements for notification to other parties because the volume of gas to be injected will be for small volumes and for a limited duration on an annual basis.
b. Whether the applicant has the right to inject gas into the target formation.
c. If the injected fluid contains H2S (sour gas). An up-to-date, AER-approved emergency response plan as per Directive 071 must be in place.
d. Proof of Directive 051 approval is required prior to commencement of injection.
e. The applied for maximum wellhead injection pressure (MWHIP) and justification if the MWHIP is above Directive 065, Appendix O, Table 1
f. The applied for maximum daily gas injection rate
g. The cumulative days required on an annual basis, for the temporary injection and indicate the total number of years required.
h. Specify the cumulative gas volume on an annual basis.
The application can be found in EAS under Directive 065, Gas Injection – ST.
