Requirements
Comments
c) porosity and permeability of the
disposal zone,
d) viscosity of the injected fluid and the
reservoir fluid, and
e) the distance between the proposed
disposal well(s) and any hydrocarbon
pool or accumulation.
6) An interpreted and annotated log crosssection
or representative well log(s) showing
a) stratigraphic interpretation of the
zone(s) of interest,
b) interpretation of the fluid interfaces
present,
c) completions and treatments to the
wellbore(s), with dates,
d) cumulative production,
e) finished drilling date and kelly bushing
(KB) elevation, and
f) the scale of the log readings.
Conservation
If disposal is to occur into a hydrocarbon pool or an associated aquifer, it must be evident that
it will not have a detrimental effect on ultimate hydrocarbon recovery from the pool.
If the proposed disposal well is more than 1.6 km from any hydrocarbon pool or
accumulation, you may omit requirements relating to conservation.
Requirements
Comments
1) Identification of the ERCB-designated pool
to receive the disposal fluid and/or any
ERCB-designated pool within 1.6 km of the
proposed disposal well.
2) A statement on whether incremental
hydrocarbon recovery is anticipated as a
result of the proposed injection. If it is, state
the incremental volume relative to the
original oil in place (OOIP).
If incremental recovery is anticipated as a
result of the proposed injection, consider
applying for enhanced recovery rather than
disposal.
