important to enter the correct identifier. If the event sequence is not known or available, enter
the “0” event and note this uncertainty in the Application attachment.
Injection Interval: The top and base depth of the injection interval.
Porosity Interval: The porosity top and porosity base depth of the reservoir proposed for
injection.
Fluid Interface: The current gas/oil and oil/water depths (if applicable) in the reservoir
proposed for injection. These depths may be measured or estimated.
11) What type of injection fluid, as identified by Directive 051, will be used?
Multiple injection fluids may be selected. Further descriptions of the injection classes are in
Directive 051.
11a) If an injection fluid contains H 2 S and an emergency response plan (ERP) is required,
the ERCB must ensure that an up-to-date ERP is in place prior to its decision on the
application.
Is an ERCB-approved ERP incorporating the proposed scheme in place?
If no, a discussion addressing the status of the ERP must be included in the Application
attachment, in accordance with Directive 065.
There are additional environmental and safety concerns that need to be addressed when the
injection fluid contains any H 2 S. Therefore, the ERCB must ensure that the need for the ERP
has been addressed and if one is required that the ERCB Operations Group has approved an
ERP that encompasses the proposed scheme prior to making a decision on an application.
YES means that an ERCB-approved ERP incorporating the proposed scheme is in place.
NO means that either an ERCB-approved ERP incorporating the proposed scheme is required
but not in place or that an ERP is not required. For either situation, an explanation must be
provided.
ERPs should be forwarded directly to the ERCB Operations Group for review. See Directive
071 for further details on emergency response planning.
12) Will injection commence in all proposed injection wells within three months of receipt of
approval?
If no, a discussion addressing the anticipated commencement of injection and the reason
for the delay must be included in the Application attachment, in accordance with
Directive 065.
YES means that injection will begin within three months of the date of approval. This
commencement of injection date will be a condition of the approval.
NO means that injection will not begin within three months of receipt of approval. Provide
reasons for the delay in the commencement of the injection date beyond the standard threemonth
period. If injection will not begin within three months, the ERCB will generally not
