Directive 065: Resources Applications for Oil and Gas Reservoirs ...

An application for approval to commingle production must include the information for those items as
specified in the table above and as described below.
Requirements
1) A statement of what is being requested,
including
a) a reference that the application is being
made under Section 3.050 of the OGCR,
and
b) if approval for commingling is requested
on a well or pool basis, the name of the
well(s) and pools that are the subject of
the application, together with
identification of each productive interval
(kelly bushing [KB] elevation, in
metres) in each well of interest from
which you propose to commingle
production, or
Comments
If the pools involved have not been defined
by the ERCB at the time of application, the
pools should be referred to as undefined.
Inclusion of the intervals ensures that there is
no confusion about the pools involved, which
might occur if the ERCB and an applicant
have different terminology for the same
zones.
c) if an area-based commingling approval
is being requested, a list of the sections
in the area of application and the zones
to which the commingling would apply,
together with a geophysical log of a type
well with annotations identifying the
subject zones.
2) A discussion of the reasons why you are
requesting commingling, including, as
appropriate,
a) a statement of the DE or SD criteria
that were not met or the operational
issues that would be addressed by
commingling, and
b) justification as to why commingling
should be granted, including, where
required,
(i) why commingling will not
contaminate any non-saline water
interval, with supporting technical
evaluation as appropriate,
(ii) why commingling will not cause
any issues in the water well(s), with
supporting technical evaluation,
including
• the geological setting of the
shallowest perforated zone and
water-bearing zone(s),
• the details of the fracture
stimulation proposed or done,
and
In general, improved economics with
commingling alone or the ability to conduct
fewer tests under a commingling approval
are not considered valid reasons for an
application.
Your discussion of why commingling should
be permitted should draw on the information
and evaluations included elsewhere in the
application.
