Comments
5) A discussion of the maximum expected area
of influence surrounding the proposed well
over the life of the scheme, including a
discussion of any pressure gradients that
exist as a result of past or current production
or injection operations.
6) Confirmation that all wells within the area
of influence have been completed or
abandoned in such a manner that they will
not provide a path for the migration of the
injected fluid or substance to another
formation.
Oilfield or industrial waste fluids must not be
disposed into a zone that has current
production or the potential for future
production.
7) In the case of slurry fracture injection of
sand, details of the surface elevation
monitoring that will be done within 800 m
of the proposed disposal well to monitor the
impact of slurry fracture injection of sand
above the formation fracture pressure.
8) Injection logs and analysis in accordance
with Directive 051.
Confirmation of hydraulic isolation is
required before the ERCB will issue an
approval for waste disposal. This requirement
differs from Class II-IV disposal because of a
greater concern about waste contamination.
For more details see General Bulletin (GB)
2000-8.
9) Evidence of compliance with the completion
and testing requirements in Directive 051.
