Table 3.2 Summary of Requirements for Commingling on a Well, Pool, or Area Basis
Reason for Filing a Commingling Application
1. There is actual or anticipated water production equal to or greater than
5 m 3 /month in a well with perforations above the BGWP.
2. There is a water well within a 600 m radius with a total depth less than 25 m
from the top of the perforations of the well proposed for commingling.
Requirements for Application
1, 2(a), 2(b)(i), 3-6, 9, 12-16
1, 2(a), 2(b)(i), 2b(ii), 3, 4, 7-9,
12-16
3. There is H 2 S in the proposed commingled production stream. 1, 2(a), 2(b)(iii), 3, 4, 9-16
4. The proposed commingling is for
• nonassociated and associated gas,
• oil and nonassociated gas,
• oil, associated gas, and nonassociated gas, or
• oil pools (any combination of new completions and existing producing
completions) having wells capable of producing a commingled flow rate
more than 3 m 3 /d.
5. The reservoir pressure of a pool or interval proposed for commingling exceeds
90 per cent of the lesser of the closure or breakdown fracture pressure of one
of the other pools or intervals proposed for commingling.
1, 2(a), 2(b)(iv), 3, 4, 12-16, 19
1, 2(a), 2(b)(v), 3, 4, 12-15, 17
6. There are unresolved equity issues with respect to the proposed
commingling.
1, 2(a), 2(b)(vii), 3
7. The well is in a designated oil sands area or is in a pool overlapping a
designated oil sands area.
1, 2(a), 3, 4, 12-16, 20
8. A pool proposed for commingling is subject to an existing or proposed
enhanced recovery scheme.
1, 2(a), 2(b)(vi), 3, 4, 12-16, 18
9. Area-based commingling is desired. 1, 2(a), 2(b)(vii), 3, 4, 9, 12-16,
21
10. Commingling of production would involve an operational issue not specifically
detailed in Directive 065.
All requirements are to be cited
in the application. For any
requirement not applicable to
the situation, the applicant must
indicate that the requirement
does not apply.
