going on injection in order to ensure that
hydraulic isolation of the disposal interval
exists at the wellbore and that the disposal
fluid will enter the intended reservoir
interval.
The ERCB will permit injection of up to
500 m 3 of water to obtain the required
isolation logs.
If you have met Directive 051 requirements
for the proposed disposal wells, you must
include the completion logs and associated
discussions required by the directive. The
ERCB will then handle all matters pertaining
to the completion approval(s) concurrently
with the scheme approval.
If you have not met Directive 051
requirements, disposal may NOT
commence until you have received a letter
from the ERCB stating that the Directive
051 requirements have been met and
injection can commence.
3) If you are requesting an extension to the
three-month Directive 051 submission date,
provide
a) the proposed submission date, and
b) the reasons(s) for needing the
submission date extension.
Disposal well approvals issued in advance of
Directive 051 requirements being met will
contain a clause requiring that the Directive
051 information be submitted within three
months of the approval’s issue date. If three
months is not sufficient time to meet the
Directive 051 requirements, you must request
an extension.
4) When submitting Directive 051 information
after the approval has been issued, you
should provide the field and pool name, the
disposal scheme approval number, and the
well location(s).
If the Directive 051 requirements are not
submitted within the three months or other
approved timeframe, ERCB staff will rescind
the approval or portion pertaining to the
subject wells. For more information on
submission requirements and the disposal
approval process, see ERCB General Bulletin
(GB) 2000-8.
