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

Oilfield or Industrial Waste Fluid (Class I) Disposal
The following are further requirements pertaining to Class I disposal only. Note that
generally you must obtain a surface facility approval from the ERCB Facilities Waste
Management Section and/or Alberta Environment before the ERCB may issue a waste
disposal well approval. For more information on waste facility applications, see ERCB
Directive 058. You may obtain information on industrial waste facilities applications from the
appropriate Alberta Environmental Corporate Regional office.
Requirements
1) Evidence of notification to and consent from
the surface owner and/or occupant within a
radius of 0.5 km from the proposed disposal
well.
Comments
In view of the possible hazardous nature of
waste disposal fluids, extra precautions are
taken to ensure containment.
2) Evidence of notification to and consent from
potentially adversely affected parties (unit
operators, approval holders, well licensees,
mineral lessees, and/or mineral lessors)
within a 1.6 km radius of the proposed
disposal well.
If a pool is subject to unit operations or other
approvals, in most cases you may notify the
unit operator or approval holder on
behalf of the relevant group having an
interest in the pool. Otherwise, you should
normally notify individual well licensees.
3) Evidence of your right to dispose into the
proposed zone.
Proof of the right to dispose in a formation is
as follows:
• unleased Crown land—a letter of consent
from the Crown,
• Freehold lease land—consent from the
Freehold mineral holder, and
• leased by other than the applicant—a letter
of consent from the lease holder.
4) A discussion of the geological setting of the
proposed disposal zone, including the
integrity of the base and caprock and the
stratification within the reservoir and
reservoir parameters, giving vertical and
horizontal permeabilities, thickness, and
areal extent.
