grant GPP at the time of the ER approval due to conservation concerns. The ERCB may
decide to grant GPP after written notification to the ERCB that injection has begun.
Proposed Approval Area
This section must only be completed for new ER schemes and amendment types requesting to
amend the approval area.
13) Is the entire proposed approval area within the ERCB’s Pool Order boundary for the
subject pool?
YES means that the entire proposed approval area is within the ERCB’s current Pool Order
boundary for the subject pool.
NO means that the proposed approval area extends beyond the ERCB’s current Pool Order
boundary for the subject pool. The ERCB cannot approve ER approval areas larger than the
Pool Order boundary. Differences in pool delineation should be addressed prior to submission
of the ER application. Note that the approval area will not include injectors without
hydrocarbon pay, but such injectors may be listed in the approval.
The ERCB’s Pool Order boundaries are on the ERCB’s Web site under the Board Order
System (BOS) at www.ercb.ca.
14) Does your interpretation of pool extent correspond to the ERCB’s Pool Order boundary
for the subject pool?
YES means that your interpretation of pool extent coincides with the area identified by the
ERCB’s current Pool Order boundary for the subject pool.
NO means that your interpretation of pool extent does not coincide with the area identified by
the ERCB’s current Pool Order boundary for the subject pool.
The ERCB’s Pool Order boundaries reflect quarter section for wells with oil pay and one
section for wells with gas pay.
15) Is the difference in pool delineation interpretation pertinent to the proposed ER scheme,
in accordance with Directive 065?
Provide a discussion of the difference in pool delineation and the pertinence to the
proposed ER scheme in the Application attachment, in accordance with Directive 065.
A difference in pool delineation is considered pertinent if it affects any of the following
aspects of the proposed ER scheme: approval area, approval conditions, notification, or
approved injection wells.
Pool delineation is very important to the ERCB’s review of any ER scheme. The assessment
of the effectiveness of the proposed scheme relative to the optimal depletion strategy for the
entire pool requires that overall pool delineation be known. Also, accurate pool delineation is
necessary to allow for the identification of possible equity concerns involved with the
proposed ER scheme.
