Acid gas injection in Western Canada occurs over a wide
range of formation and reservoir types,acid gas compositions
and operating conditions.Injection takes place in deep saline
formations at 27 sites,into depleted oil and/or gas reservoirs at
19 sites and into the underlying water leg of depleted oil and gas
reservoirs at 4 sites.Carbonates form the reservoir at 29 sites
and quartz-rich sandstones dominate at the remaining 21 (Figure
5.13).In most cases,shale constitutes the overlying confining
unit (caprock),with the remainder of the injection zones being
confined by tight limestones,evaporites and anhydrites.
